Green Day was originally part of the punk scene at 924 Gilman Street in Berkeley, California. The band's early releases for independent record labelLookout! Records earned it a grassroots fanbase. Nevertheless, its major label debut Dookie (1994) became a breakout success and eventually sold over 10 million copies in the U.S. and 15 million worldwide. As a result, Green Day was widely credited, alongside fellow California punk bands The Offspring and Rancid, with reviving mainstream interest in and popularizing punk rock in the United States. Green Day's three follow-up albums, Insomniac, Nimrod and Warning did not achieve the massive success of Dookie, but they were still successful, reaching double platinum, double platinum, and gold status respectively. Green Day's 2004 rock operaAmerican Idiot reignited the band's popularity with a younger generation, selling five million copies in the U.S. The band's eighth studio album, 21st Century Breakdown, was released in 2009.
Insomniac is the fourth studio album from the punk rock band Green Day. It was released on October 10, 1995, through the Reprise Recordslabel. Though it reached number two in the United States and went double Platinum (According to the RIAA) by 1996, Insomniac did not have the sales endurance of its predecessor, Dookie, largely due to its slightly darker lyrical tone and heavier, more abrasive sound. The album is the band's third-best selling album behind Dookie and American Idiot with over 8 million copies sold worldwide.
