Tim Armstrong

Perhaps best known as the driving force behind '90s punk mainstays Rancid, Tim Armstrong also played bass in Operation Ivy, the other seminal post-golden years punk rock band, and is the proprietor of Hellcat Records, which put out Joe Strummer's last few albums. In 1999, Armstrong launched a punkified hip-hop group, called the Transplants, and to date has released a trio of records with them. In the meantime, Armstrong has made appearances alongside all kinds of acts, from Gwen Stefani and Pink to such more seemingly suitable projects as Bad Religion and NOFX. In 2007, Armstrong released his first proper solo album, a good time reggae-punk record, called A Poet's Life.
