A longtime friend of the band, even appearing in the ‘When I Come Around’ video, Jason first joined them onstage in 1999 at the Bridge School Benefit and continued on with the subsequent Warning tour singing backing vocals and playing lead guitar. Along with Green Day, he also is a member of their side projects, The Network and Foxboro Hot Tubs, and is also in Pinhead Gunpowder along with Billie. In 2012, Jason became a full-time member of Green Day joining them in the studio to record what would become a trilogy of albums, ¡Uno!, ¡Dos! and ¡Tre!. After the touring cycle of the trilogy wrapped up, Jason went back to being a touring member and the band recorded their follow-up album, Revolution Radio, as a three-piece again. In 2014, Jason was diagnosed with tonsil cancer which required him to have his tonsils removed. He made full recovery and he is now cancer free. Outside of his Green Day related projects, Jason has also played in California, The Influents, The Big Cats and more.
