A veteran of the Denver music scene, Jack Hadley has fronted his own blues-based act for close to a decade; he also spent a year and a half as lead guitarist in Otis Taylor's band, and played reggae with Rude Culture and R&B and funk with Network. Hadley knows his way around the blues, and he definitely adds a sense of professionalism to his weekly Monday jams at Jack's. While other blues jams around town attract their share of novices, Hadley's jams bring in more seasoned players, who come to play on the venue's pro sound system. A limited backline is also provided.
