Ozric Tentacles - Jurassic Shift
Outstanding choice. I've found Live Underslunky to be a great 'road CD' as well.
One of the joys of plugging my iPod into my car stereo is telling it to play all Ozrics songs at random, which -- on that iPod, and including the great Boulder CO 2-disc show -- adds up to around 13-14 hours of musical bliss.
