Great Lakes Reverberation John J. Callahan, PhD POW!/WCSB Joining POW! In the summer of love, 2019, John Callahan, co-host of the Friday Night Rock Rotation, has been a conspicuous presence on WCSB for 15 years. John is known for spinning modern psych in the vein of Velvet Underground, Spacemen 3, and the Brian Jonestown Massacre (BJM). Interviews of his favorite artists are also his thing. The Magnetic Fields, Dream Syndicate, Black Angels, and Dandy Warhols have all shared the airwaves of the Rock Rotation. John’s first review/interview dates back to 1991 when he shot the chit-chat with shoegaze legends Chris Acland and Emma Anderson of Lush. Today its spacing out with Fuxa, Pontiak, and Kim Gordon for the love of all things rock ‘n’ roll. It’s coffee over Moon Duo as he plots his next interviews with the Warlocks, Stereolab, and King Khan. Oh yeah, Dr. Callahan is a life long special education teacher, swimmer, and Dad. You can find his super-sharp wife and family leading the way into Cleveland-area record stores and flower gardens.
