Best known for his membership in the 1970s and '80s rock band Chicago, this drummer, songwriter, and music producer contributed to most of the band's hit albums, including the Double Platinum Chicago V. In 2006, he formed another band, the California Transit Authority, that released a debut album titled Full Circle.
After dropping out of high school at age fifteen, he took lessons with drummer Bob Tilles through DePaul University's music department.
He helped write such Chicago songs as "Street Player," "Lowdown," and "Birthday Boy."
He was born and raised in an Italian neighborhood of Chicago, Illinois. He later settled in Los Angeles, California.
When Seraphine, guitarist Terry Kath, and saxophonist Walter Parazaider first formed the band that would become Chicago, they called their music group several different names, including The Big Thing, The Missing Links, and The Chicago Transit Authority.
