Enigmatic masked DJ/producer Marshmello makes groove-oriented, synth- and bass-heavy electronic dance music. In the spirit of other masked DJs like Deadmau5 and Daft Punk, Marshmello (whose real identity remains a mystery) appears wearing a full-head-covering marshmallow mask. Despite the anonymity, Marshmello's career blew up in 2015 when he began releasing tracks online, including remixes of Zedd's "Beautiful Now," Jack Ü's "Where Are U Now," and others. From there came shows at New York's Pier 94, Pomona, California's HARD Day of the Dead festival, and Miami Music Week. In 2016, Marshmello released a compilation of his previously released tracks, Joytime, which reached number one on a digital top electronic albums chart. Included on the album was the single "Keep It Mello," featuring rapper Omar LinX.
