A new movement in the mainstream became visible in the early and mid-1990s, claiming to be a form of punk, this was characterized by the scene at 924 Gilman Street, a venue in Berkeley, California, which featured bands such as Operation Ivy, Green Day, Rancid and later bands including AFI, (though clearly not simultaneously, as Rancid included members of Operation Ivy, who had broken up 2 years prior to the formation of Rancid).
