Green Day is an alternative rock band, that has put out 5 albums. Their first album was 1,039/Smoothed Out Slappy Hours, which came out in 1990 from Lookout Records. This contained the songs their previous EPs: 1,000 Hours, Slappy, and 39 Smooth. This is includes the song Green Day that they're named after. Their next album was Kerplunk!, from Lookout in 1991, which made them popular nation-wide. This included the song Sweet Children, which is the original name of the band. After Kerplunk!, Green Day went to Warner Brothers' Reprise Records, which was bigger than Lookout. Their first album with Reprise was Dookie, in 1994, which has sold over 8 million copies. After Dookie, Green Day's lead singer, Billie Joe Armstrong, got married and had a baby. Green Day was at Woodstock '94, and their performance turned into a mud fight after an audience member threw mud at Billie Joe, he caught it in his mouth, and threw it back. It resulted in people throwing more mud and running onto the stage. When security guards were trying to get the people off the stage, they "mistakenly" tried to throw Mike off as well, despite him saying that he was with the band. Their fourth album with Reprise is Insomniac. Billie Joe says it is named Insomniac because most of it's songs were written during sleepless with his new baby. Since Insomniac, Tre has also gotten married. Thier fifth album is nimrod.It came out October of '97.The album is very energetic ,and is a very experimental album ,that's what I think at least.I hope you enjoy the pictures I have.
