Favorite tracks: They're all good. The DVD-A is a treasure trove of newly unearthed surround mixes and unreleased tracks Zappa produced between 1970 and 1979. "Ship Ahoy" is a live concert recording and contains a particularly inspired FZ guitar solo--and the three-dimensional, you-are-there presence of the sound is thrilling. "Chunga Basement" feels like a totally improvised tune; it was recorded "live" in the studio, direct to four-track tape, and mixed in surround. Quaudiophiliac's recording quality doesn't sound the least bit dated; its dynamic range and full-frequency response trounce most contemporary recordings. Old fans and Zappa novices will cherish this disc.

Favorite tracks: "Distant Shore" is a tasty blues workout; it features an edgy keyboard groove easing out of the surround speakers. Drums shine throughout the disc, and if your system's up to snuff, they'll have the dynamic kick of the real thing. We spot-checked the Dual Disc's CD side's sound, but once you're acclimated to high-res sound, it's tough to go back. "Time Makes Two" scales the blues heat back to a simmer, but we could almost see Cray down on his knees.

Favorite tracks: The strange and hauntingly beautiful tune "Shadows Part 2" stayed in heavy rotation in our home theater. Its sound effortlessly glides fore and aft in the surround field, or at least it should in a properly arranged system. Dave Matthews's vocal graces the most engaging tune on the DVD, "Sing Along." On "I Feel Love," the blue guys cover Donna Summer's classic and replace the original's sleek synths with acoustic drums and thrashing guitars. To fully experience the Blue Man Group's densely percussive music, you'll need a set of really good speakers and a very potent amplifier. The music's head-turning dynamics and feel-it-in-your-toes deep bass will surely put your sub though an aerobic workout.

Favorite tracks: Gotta go with "Weapons of Mass Distortion" because of the way its extracrunchy heavy-metal guitars thrash and burn and finally dissolve into a "Tubular Bells"-like theme. "Realizer" energized our theater--the mix dances around the complete speaker array, its throbbing grooves are constantly on the move. Unlike most 5.1 mixes that treat the surround channels as gimmicky effects, the Crystal Method never distinguishes between front and rear speakers. The sound is everywhere, but the logic to the mix becomes apparent over repeated listening sessions.

Favorite tracks: We can't pick out just one or two tracks; the entire DVD is flat-out amazing. OK, the movie may now seem overly sentimental and trite to jaded modern audiences, but John Williams's score is a wild ride of strings, blaring horns, and ethereal choirs. The high-contrast sound is oh so vivid, replete with soaring dynamic leaps. It's stereo only, but even on a halfway decent home theater, its holographic imaging and astounding depth will blow you away.
