I've got to second Trelja's recommendation for Lucinda Williams "Car Wheels On A Gravel Road"-- on trks #7 and #12, the soundstage is wide and deep with percussion and other instruments exploding all over the place. It should be noted that this is an HDCD recording. Cowboy Junkies "Trinity Sessions" is also excellent. I also like all of the Enigma CDs for bass excitment. Cheers. Craig.
