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 is largely believed to be Christopher Comstock aka Dotcom) appears wearing a full-head-covering marshmallow mask. Despite the anonymity, Marshmello's career blew up in 2015 when he began releasing tracks online. From there came shows at New York's Pier 94, Pomona, California's HARD Day of the Dead festival, and Miami Music Week. He also scored a number five Billboard electronic/dance album with his full-length debut, Joytime, and followed up with collaborative hits with artists like Selena Gomez ("Wolves") and Khalid ("Silence").
A native of Philadelphia, Pennsylvania, Christopher Comstock relocated to Los Angeles and began producing and DJ'ing under the name Dotcom before adopting the stage persona of Marshmello. In 2015, he began anonymously posting songs to his SoundCloud page, including remixes of Zedd's "Beautiful Now," Jack Ü's "Where Are U Now," and others. Soon, he was drawing fans and gaining vocal support from peers like Skrillex, who reposted Marshmello's track "Find Me." High-profile live DJ appearances followed, including shows at Ultra Music Festival, California's HARD Day of the Dead festival, and more. In 2016, Marshmello released a compilation of his previously released tracks, Joytime, which reached number five on the Billboard electronic/dance albums chart and number one on a digital top electronic albums chart. Included on the album was the single "Keep It Mello" featuring rapper Omar LinX.
Also in 2016, after a set at Electric Daisy Carnival, Dutch DJ Tiësto jokingly emerged from under Marshmello's mask, fallaciously proclaiming he was the mysterious DJ. However, in a 2017 Forbes article, it was revealed that Comstock was in fact the man behind the mask, with the magazine pointing to BMI and ASCAP royalty credits as proof. Nonetheless, Marshmello never officially revealed his identity. He continued to perform and release singles throughout the year, later starting his own Joytime Collective record label. More collaborations followed in 2017, including "Silence" with Khalid and "Wolves" featuring Selena Gomez. In 2018, Marshmello paired with British vocalist Anne-Marie for the single "Friends." Also that year, he delivered his second full-length album, Joytime II, which included the singles "Tell Me" and "Check This Out."
