One performance worth hearing is from 1977. West Texas State University Symphonic Band, appearing at TMEA(Texas Music Educator's Association) convention in San Antonio, Feb. 1977. Is a record, and I don't believe there's a CD version, unless you find someone who's dubbed it over.
Be aware that the record recording is sped up a bit, so is sharp to A-440. The original tape, which I've heard first hand, is at the correct speed/pitch. If I remember correctly, there was a capacity issue going from tape to disc.
Quite a good recording of Czardas. Also has Creston Concerto, 2nd movement.
Ebay and the usual sources to find, I suppose.
