Christopher Comstock, known professionally as Marshmello, is an American electronic dance music producer and DJ.
He first gained international recognition by remixing songs by Jack Ü and
Zedd and later collaborated with artists including Omar LinX, Slushii, Jauz, Migos, Ookay, Khalid, Selena Gomez,
Anne-Marie, and Logic.
Marshmello wears a custom helmet for public appearances. His identity was unknown, but was confirmed to be Chris Comstock in late 2017 by Forbes.
His musical style includes groove-oriented, synth and bass-heavy electronic dance music. Inspired by other masked DJs like deadmau5 and Daft Punk, Marshmello appears wearing a full-head-covering white coloured bucket. Despite the anonymity, his career received international recognition in 2015 when he began releasing tracks online, including remixes of Zedd's "Beautiful Now", Jack Ü's "Where Are Ü Now" and others, as well as his own single "Alone".
