Photos from the Columbia Records 30th Street Studio Don Hunstein was Columbia Records’ in-house photographer for 30 years, and he snapped photos of Bob Dylan, Johnny Cash, Billie Holiday, Muhammad Ali, and Charles Mingus, to name a few. The Morrison Hotel Gallery's Soho loft (116 Prince Street, NYC) is now hosting a new exhibit of his photos, "In Session at the Columbia Records 30th Street Studio." Grammy-winning producer, writer and record executive Michael Cuscuna has also met and worked with many of the artists featured in the Morrison exhibit.
