As the guitarist and vocalist of the band Biohazard, Billy Graziadei has seen some wild stuff during his career.

Billy explains to us how he discovered BJJ way back in 1993, and how he was able to keep training even during epic 18-month long band tours.

From choking people out while on tour to organising back-stage roadie challenge matches, this episode has a lot of fun stories.
