Billie Joe Armstrong (born February 17, 1972) is an American rock musician and occasional actor, best known as the lead vocalist, main songwriter, and guitarist for the American punk rock band Green Day, which he co-founded with Mike Dirnt. He is also a guitarist and vocalist for the punk rock band Pinhead Gunpowder and provides lead vocals for Green Day's side projects Foxboro Hot Tubs and The Network respectively. Raised in Rodeo, California, Armstrong developed an interest in music at a young age, and recorded his first song at the age of five. He met Mike Dirnt while attending elementary school, and the two instantly bonded over their mutual interest in music, forming the band Sweet Children when the two were 15 years old. The band changed its name to Green Day, and would later achieve massive commercial success.
