Help Finding a recording

[KevinMadden]

So I'm working up the Wilder Sonata for Tuba and am Having some trouble tracking down an audio recording.
I figure Harvey Philips probably did a recording of this, as it's dedicated to him, but amazoning or googling Harvey really doesn't come up with much. Searching for Wilder gets a lot of hits of Effie and his other stuff, but not alot of the Tuba Sonata.

Help would be appreciated.
