The Hollywood Reporter revealed on Wednesday (March 5) that Armstrong has joined fellow Oaktown legend rapper Too $hort as part of the ownership

The privately owned club — it was founded by former head of comedy at Fusion Bryan Carmel and his Oakland boyhood friend and edtech entrepreneur Paul Freedman, with the help of outside investors — offered fans a chance to join a $1.2 million financing round last year. Some 2,200 of them signed up. A $2 million round is planned for this year.

Armstrong, 53, founded Green Day in 1987 with Mike Dirnt. The band has sold more than 85 million records worldwide and has won four Grammy Awards. Armstrong also won a Grammy for Best Musical Show Album for “American Idiot,” which also featured Green Day.
