Here's another recording studio mystery photo. It's the Columbians Dance Orchestra, a Columbia studio dance band comprising older 'house' musicians and young dance band players, under the direction of Robin Hood Bowers. The photograph was taken at the Columbia studios in the Gotham Bank Building, Broadway and 59th Street, New York, in c. October 1921. Our good friend and researcher Bjorn Englund points out the the picture was used in a Record Research feature in July 1969 on trumpeter Herman 'Hymie' Farberman, who provided the following personnel:- (L-R) Billy O' Gorman, Rudy Wiedoeft, Sam Feinsmith, Hymie Faberman, unknown drummer (possibly Columbia staff musician Edward Rubsam, whose career at Columbia went back to the company's earliest days), Harry Reser, Robert Hood Bowers (director), unknown piano (possibly Hugo Frey), Marty Berger trumpet, Ephraim Hannaford, John 'Pop' Helleberg. Note the music clips hanging from the ceiling, suspended from laterally-strung wires so that they can be easily repositioned.
