Victor's first commercial electrical recording was made at the company's Camden, New Jersey studios on February 26, 1925. A group of eight popular Victor artists, Billy Murray, Frank Banta, Henry Burr, Albert Campbell, Frank Croxton, John Meyer, Monroe Silver, and Rudy Wiedoeft gathered to record "A Miniature Concert". Several takes were recorded by the old acoustical process, then additional takes were recorded electrically for test purposes. The electrical recordings turned out well, and Victor issued the results that summer as the two sides of twelve inch 78 rpm record Victor 35753. Victor's first electrical recording to be "issued" was Victor 19626, a ten inch disc consisting of two numbers recorded on March 16, 1925 from the University of Pennsylvania's thirty-seventh annual production of the Mask and Wig Club, issued in April, 1925. On March 21, 1925, Victor recorded its first electrical Red Seal disc, twelve inch 6502 by pianist Alfred Cortot, of pieces by Chopin and Schubert.
