Overview of Green Day's Core Members
Green Day is a Berkeley, California–influenced punk rock band whose best known lineup consists of three members: Billie Joe Armstrong on lead vocals and guitar, Mike Dirnt on bass and backing vocals, and Tre Cool on drums and percussion. Formed in 1986 and originally called Sweet Children, the band released early work on Lookout! Records before moving to Reprise/Warner Records.
