<span>Once celebrated as the greatest voice of her generation, Whitney Houston died in a Beverly Hills bathtub, at the age</span><span> of 48 and decidedly down on her luck. But </span><span>intrigue in her enduring work and tragic life </span><span>has only grown since her death</span><span> in February 2012.</span> <span>New products and fresh revelations help to feed </span><span>such fascination</span><span>, </span><span>naturally sparked by </span><span>the singer's premature death</span><span>, while </span><span>public interest is fuelled further by last year's stark documentary portrait </span><span><em>Whitney</em></span><span>. Houston's final album</span><span><em> I Look To You</em></span><span> was released </span><span>10 years ago </span><span>last week</span><span>, but it has been far from the final word from Houston – </span><span>it was simply the last one </span><span>she had any say in.</span> <span>The voice of 11 Billboard </span><span>No 1 hits in her lifetime – including</span><span> her timeless cover of Dolly Parton's overwrought romantic ballad</span><span> </span><span><em>I Will Always Love You</em></span><span> – last month Houston scored her first top </span><span>10 hit from beyond the grave with </span><span><em>Higher Love,</em></span><span> a cover of Steve Winwood's blue-eyed soul number, based on vocal parts recorded for her third album, </span><span><em>I'm Your Baby Tonight</em></span><span> (1990). </span> <span>Produced by and co-credited to Norwegian </span><span>DJ Kygo, this floor-filling electronic version topped the US d</span><span>ance charts, but has stoked controversy among fans of Houston</span><span>, not least for a regressive video </span><span>that depicts a troupe of female dancers being eagerly watched by lusty males.</span> <span>"This music video is the estate of Whitney Houston in a nutshell: </span><span>cheap, tacky, nothing like Whitney," stated Instagram fan account @whitneyhoustonthelegacy. "This video is the exact opposite of everything she stood for as an artist</span><span> and if you are a fan, you should know it."</span> <span>But</span><span><em> Higher Love </em></span><span>is unlikely to prove the most controversial statement from Houston's estate, which after years of respectful distance recently announced a </span><span>series of new money</span><span>-making</span><span> plans – including a potential new album, a Broadway show</span><span> and </span><span>several branding and licen</span><span>sing partnerships. Th</span><span>at la</span><span>st proposal could </span><span>lead to the singer's voice being used to help</span><span> sell products she had never heard of in her lifetime, let alone endorsed. </span> <span>More contentious still are plans for the ultimate commodified novelty treatment – a touring Houston hologram, arguably the most divisive trick that can be pulled on a deceased star's memory. Musicians including renowned opera singer </span><span>Maria Callas, rockabilly treasure Roy Orbison and famous rock</span><span>er Frank Zappa have </span><span>all been brought back to life in hologram form</span><span>, as has Houston's former romantic partner, Michael Jackson</span><span>. </span><span> </span> <span>A 3D Houston representation has been </span><span>in development for years</span><span> and sources even suggest the </span><span>Houston hologram will "sing" hits </span><span>such as </span><span><em>Saving All My Love for You</em></span><span> and </span><span><em>The Greatest Love of All</em></span><span> "live" alongside the star's original band members and singers. Call it karaoke in reverse.</span> <span>In May, the Houston estate signed a multi-million-dollar deal with Primary Wave Music Publishing, a "boutique" agency </span><span>that has interests in</span><span> aging acts such as Smokey Robinson, Paul Anka and Def Leppard, and which last year controversially acquired a share in Bob Marley's evergreen catalogue.</span> <span>As part of the agreement, Primary Wave will </span><span>have the right to </span><span>use Houston's name and likeness for advertising campaigns and sponsorships, as well as enjoying 50 per cent of royalties from the singer's music, film and merchandise. That </span><span>decision to sign that deal was ultimately </span><span>made by one person – with the singer's sister-in-law and former manager, Pat Houston, listed as the sole executor of the estate.</span> <span>"It's been quite emotional for the past seven years," Pat Houston </span><span>told the </span><span><em>New York Times</em></span><span> at the time of the deal. "But now it's about being strategic."</span> <span>Not much </span><span>is known about her planned strategy</span><span>, but we can surely expect a full-blown assault in advance of the </span><span>10th anniversary of Houston's death, in 2022. However, can we hope for any new music? It's rumoured that dozens of unused tracks may exist from mid-1980s sessions for Houston's first two albums, but it is unclear how complete or marketable these outtakes and offcuts</span><span> are, or from where else a whole album of fresh material might be sourced.</span> <span>So far, Houston's archives have dodged the kind of comprehensive ransacking </span><span>that has typically followed the death of an A-lister</span><span>. </span><span>Superstars Prince and Avicii </span><span>released </span><span>"new" albums from beyond the grave in June</span><span>.</span> <span>In total, five fresh Houston singles have trickled out in the past six years</span><span>, of varying worth and insight. </span><span><em>Higher Love</em></span><span> marked the second time Houston's </span><span>vocals have been digitally transplanted on to a new production, with 2016 welcoming a well-received virtual duet with Siti Nurhaliza on </span><span><em>Memories, </em></span><span>originally </span><span>written by</span><span><em> </em></span><span>Hugh Hopper of Soft Machine fame.</span> <span>The release transplanted </span><span>Houston's first professional vocal recording, at the age of 19 – a relatively unheard guest slot on Material's 1982 album </span><span><em>One Down</em></span><span> – on to a new vocal from Nurhaliza, </span><span>who was 37 at the time, and released to celebrate the Indonesian singer's 20th anniversary as a recording artist.</span> <span>Whatever aesthetic concerns exist about repurposing these old vocal tracks, Houston's two posthumous duets have fared better than her final recordings, three of which were </span><span>released in the slipstream of her death in 2012. The first to </span><span>come out was the last song Houston </span><span>recorded, </span><span><em>Celebrate</em></span><span>, a duet with Jordin Sparks drawn from the soundtrack to </span><span><em>Sparkle</em></span><span>, Houston's final feature film acting role, and arguably as good a swansong as we could hope for.</span> <span>Shot three months before the singer's death, the story of a revolutionary girl group inspired by The Supremes – and a remake of the 1976 film of the same name – </span><span><em>Sparkle </em></span><span>allowed Houston to p</span><span>ay homage to the classic era of Motown. A deliberately derivative period piece, </span><span><em>Celebrate </em></span><span>was a duet with writer and producer R Kelly.</span> <span>That</span><span> pairing </span><span>may now be considered unfortunate given the #MeToo-inspired allegations against Kelly that would follow, </span><span>but </span><span>he also cropped up on a </span><span>duet version of </span><span><em>I Look to You</em></span><span> – released in September 2012 – that was used to promote </span><span>the obligatory greatest hits package,</span><span><em> I Will Always Love You: The Best of Whitney Houston</em></span><span>, which </span><span>featured </span><span>another unreleased track, the underwhelming R&B dirge</span><span><em> Never Give Up.</em></span> <span>Most telling was a second unplanned tune from the </span><span><em>Sparkle</em></span><span> soundtrack</span><span>, released a day after </span><span><em>Celebrate</em></span><span>, called </span><span><em>His Eye Is on the Sparrow</em></span><span>, a rousing gospel number once recorded in Grammy-winning fashion by</span><span> Mahalia Jackson. In the movie, the performance marks a touching moment, but </span><span>an earnest critical listen to the audio wasn't </span><span>pretty</span><span> and reveal</span><span>ed just how much Houston's voice had deteriorated in her final days – a </span><span>decline that was roundly blamed on her lifestyle.</span> <span>"Houston sings – and croaks – in a voice octaves lower than in her prime," mourned </span><span><em>Rolling Stone</em></span><span>'s Jody Rosen. "At times the song has a ravaged magnificence, but mostly it's painful".</span> <span>Hopefully, the same won't be said of whatever emerges next – but however disappointing the remaining offcuts remain, there </span><span>may soon </span><span>be a hologram of Houston waiting in the wings, ready to belt out </span><span><em>I Will Always Love You</em></span><span>. </span>
