I agree with Sdcampbell about well-recorded organ music. I'll add two more suggestions:
James Carter "Chasin' the Gypsy." On this album, Carter plays bass saxophone as a lead instrument on a number of tracks. On the first track (Nuages), in particular, he really plumbs the depths of what the bass saxophone is capable of. This is a great test of the bass response of speakers/subs.
Rusted Root "When I Woke," especially the first track (Drum Trip)
