The above link is to a cover of Duke Ellington's "Birmingham Breakdown" by a studio group called the Dixie Dance Demons, with Irving Peskin on trumpet and George Hall on violin (a quite nice solo, too) as the only identified musicians. The two trumpet solos sound so different I suspect there were two trumpeters on the date and I have no idea which one was Peskin. Both sound Bix-influenced but the first one is considerably more imaginative than the second. The "Steppin' Along" record is even more confusing: the clarinetist doesn't sound good enough to be Jimmy Dorsey in 1929 (only his upward "flare" at the end sounds even remotely like J.D.), and ditto the trumpeter, who plays without any of the double-timing that was a trademark of Mannie Klein.
