A rare collection of previously unreleased recordings of jazz legend Cannonball Adderley from the late ’60s has gone digital for the first time.

The newly issued recordings were captured live on a radio broadcast over four nights at the famous Penthouse jazz club in Seattle between 1966 and 1967, at the height of Adderley’s career.

Those recordings spent decades sitting in an archive until Canadian saxophonist and Cellar Music Group founder Cory Weeds discovered them. Now, his Vancouver-based label’s Reel to Real imprint has teamed up with New York distributor La Reserve to release Swingin’ in Seattle: Live at the Penthouse (1966–1967) for streaming on all digital platforms.
