Tre's solid and always tasteful drumming has earned him the respect as one of rock's best drummers. Growing up, Tre's closest neighbor was none other than Lookout! Records owner Lawrence Livermore, who also owned the punk band the Lookouts. At age 12, Livermore recruited Tre to join The Lookouts, and that's when Livermore gave him the name of Tre Cool. After Green Day's first tour around the country (following the release of 39/Smooth), John Kiffmeyer decided to leave the band. Looking no further than Gilman Street, Billie Joe and Mike recruited Tre, who was already a 5 year veteran of the Gilman Street scene.
