Missing Recording?

[ramanathantuba]

I recently unearthed the piece 'Præludium, Chorale, Variations, and Fugue' by J.I. Muller, which contains a tuba solo part although seems to be written for bass trombone. I was wondering whether anybody knew of a recording of either bass trombone or tuba with the piano or organ accompaniment, preferably one that is publically accessible. Thanks for the help!
