Jack Bruce has been playing Warwick basses for over 25 years, and we're very proud to have him as a Signature Endorser and dear friend. His music and playing are legendary... If you haven't seen this video yet, you must! Jack Bruce - On Life & Music. Very inspirational! He is most recently on tour with his new band, Spectrum Road - featuring Vernon Reid on guitar, John Medeski on organ, and Cindy Blackman-Santana on drums. Absolutely amazing!
