Ajram performed a set on Thursday night, which Marshmello joined her for.
The duo released the song on July 8 and have achieved international acclaim for the tune, which made it into the US Billboard Dance Charts two weeks after its initial release, becoming the first Arabic-language song to do so.
It’s also the first Arabic-language song to have made it into the Top 10 iTunes chart, and it has topped the iTunes electro-dance category in the UAE and Saudi Arabia.
Egyptian rapper Marwan Pablo also performed with the beloved singer, who made it a point to get off the stage and interact with the ecstatic crowd.
Marshmello, whose real name is Christopher Comstock, is famous for wearing a white helmet that resembles a marshmallow.
He hyped up the audience as he took to the decks and Ajram sang the playful lyrics to their history-making track.
“People are loving Sah Sah for more than one reason,” Egyptian composer Moody Saeed, who worked on the track with Ajram and Marshmello, previously told The National. “The lyrics are light and the words, sah sah, are fun and easy to remember. It’s also the music, the beat, it has a mix of East and West.”
The pair are not the only international names performing at Gamers8, an esports festival taking place in the Saudi capital.
