Russell Brand and Carl Barat played their debut gig together in Los Angeles last night (May 24).

The pair performed alongside actor Jonah Hill as Infant Sorrow - the fictional band from Brand’s new movie Get Him to The Greek.

The comedian-turned-actor appeared as his character Aldous Snow at the Roxy Theatre.

According to The Sun, the trio are also expected to release an album later this year via Universal Records.

Get Him To The Greek is released in cinemas on June 25.
