Christopher Comstock, better known by his stage name Marshmello, (born May 19, 1992) 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, Ookay, Jauz and Slushii. In January 2017, his song “Alone” appeared on the U.S. Billboard Hot 100 chart.

In 2018, he released “Friends”, a collaboration with British singer Anne-Marie which peaked in the top 20 in the US. Months later, his second studio album, Joytime II, was released with singles “Tell Me” and “Check This Out”. “Happier”, a collaboration with British band Bastille, was released in August and became his highest-charting song on the Billboard Hot 100 at #2. In 2019, he earned $40 million, ranking second on the list of highest paid DJs compiled by Forbes. In 2020, he and American rapper Juice Wrld released “Come & Go”, from the latter’s posthumous album Legends Never Die; the song reached number two on the Billboard Hot 100, matching “Happier” as his highest-charting song. In 2021, his album Shockwave earned him a Grammy nomination.

Marshmello wears a custom helmet for public appearances. His identity was unknown, but was confirmed to be Chris Comstock in late 2017 by Forbes.

Marshmello’s stage name, an alternative spelling of “marshmallow”, and his marshmallow mascot head were both inspired by Canadian electro house music producer and DJ deadmau5, who also notably uses an alternate spelling for his stage name and performs wearing a “dead mouse” mascot head.
