California-based pop-punk heroes GREEN DAY have released a video message congratulating fellow Bay Area rockers METALLICA on their 30th anniversary. The three-and-a-half-minute clip, which can be seen below, features the members of GREEN DAY performing the MISFITS classic "Hybrid Moments" in their rehearsal room.

METALLICA was formed when drummer Lars Ulrich, who had moved to Los Angeles from Denmark, placed an ad in a local paper called The Recycler looking for other musicians to play with. The ad was answered by guitarists James Hetfield and Hugh Tanner of the band LEATHER CHARM.

METALLICA officially formed in October 1981 and the band's first recording was "Hit The Lights" for the compilation "Metal Massacre".

Bay Area DJ Ron Quintana came up with the group's name: he was debating between using "Metallica" and "Metal Mania" for the name of his radio show and Ulrich encouraged him to use "Metal Mania" so that he could use "Metallica" for his new band.

METALLICA's first full lineup — featuring Hetfield, Ulrich, guitarist Dave Mustaine and bassist Ron McGovney — played its first gig on March 14, 1982 at Radio City in Anaheim, California.
