About Mike Dirnt
Michael Ryan Pritchard, better known by his stage name Mike Dirnt, is an American rock musician who is the co-founder, bassist, backing vocalist, and occasional lead vocalist of Green Day. He has also played in several other bands, including the Frustrators. His stage name Dirnt was originally a nickname that his friends from grade school gave him, as he constantly played "air bass/guitar" and made a "dirnt, dirnt, dirnt" noise while pretending to pluck the strings. Dirnt has four signature basses, including the American Fender, Mexican Fender, Mexican road worn Fender, and the new Epiphone Grabber G-3. Having been previously described as bright and fearless, Dirnt became sullen and withdrawn after the divorce. After changing its name to Green Day, the band recorded its debut album, 39/Smooth, over the 1989 Christmas holiday break and went on its first van tour in June 1990, leaving the day that Dirnt graduated from high school. In 2007, during the recording of Green Day's eighth studio album, 21st Century Breakdown, Dirnt, Armstrong, and drummer Tré Cool formed the garage rock side project Foxboro Hot Tubs.
