Mini bio
How it started.
Mike started on guitar, then picked up his mother’s pawnshop bass, which had only two strings. He met Billie Joe Armstrong in fifth grade. They played wherever they could, from backyards to school dances, before saving show money and odd-job earnings to buy a van and tour.
Finding their people.
Their band began as Sweet Children before becoming Green Day. The East Bay punk scene shaped their early years, and the touring life meant small rooms, borrowed floors and long trips in a van. Mike has stayed alongside Armstrong as Green Day’s bassist and backing vocalist.
The breakthrough.
Dookie brought Green Day to a much wider audience in 1994, with songs including “Longview,” “Basket Case” and “When I Come Around.” American Idiot followed in 2004, taking their music into an ambitious rock opera that later reached Broadway. Green Day entered the Rock & Roll Hall of Fame in 2015.
Still building songs.
For Saviors, Mike told SPIN that the band gave the songs time to develop and worked together in the same room. Alongside the records and touring, he has helped design signature instruments, including the Epiphone Grabber G-3 released in 2025.
