Mellowdrone are an alternative rock band from Los Angeles, California. The band was formed in 1999. The current members are Jon Bates (vocalist/bassist), Tony DeMatteo (guitarist) and Brain Borg (drummer).

Their debut album, Box, was released in 2006 via Columbia Records. Their follow-up, Angry Bear, was released in 2009 via Coming Home Records. Shortly after, the group disbanded. In 2017, members of The Neighbourhood who were fans of Mellowdrone contacted Jonathan and Tony for a collaboration. Both members accepted, and this ended up being the first time members of Mellowdrone had met up in eight years. The two were inspired to start writing songs together again, and Mellowdrone was eventually revived as a band. They began publishing music again independently in 2018.

Mellowdrone’s music has appeared on several television shows, including Project Runway, Six Feet Under and Cane.
