Billie Joe Armstrong

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 14 years old. The band changed its name to Green Day, and would later achieve commercial success. Armstrong has also pursued musical projects outside of Green Day's work, including numerous collaborations with other musicians.

In 1997, to coincide with the release of Nimrod, Armstrong founded Adeline Records in Oakland to help support other bands releasing music, and signed bands such as The Frustrators, AFI and Dillinger Four. The record company later came under the management of Pat Magnarella and finally shut down in August 2017.
