1) The Who, "Quadrophenia" (Universal/Geffen) The follow-up to "Tommy" wakes, shakes and increasingly swirls round through gems like "The Real Me" and "Love Reign O'er Me." Most Pure Audio Blu-rays only place a song menu on your TV screen. This one cycles through 40 images.

2) Nat King Cole, "The Extraordinary" (UME/Capitol) The king crooner scores anew in glorious monaural sound, 36 tracks deep, from "Route 66" to "Mona Lisa" and "The Christmas Song."

3) Lenny Kravitz, "Are You Gonna Go My Way" (Virgin) A red-hot rockin' showpiece. 'Nuff said.

4) John Lennon, "Imagine" (Apple/Universal) Not the greatest engineering job, but "Gimme Some Truth" and "How Do You Sleep?" loom larger.

5) Crosby, Stills, Nash & Young, "CSNY 1974" (Rhino Pure Audio) How good could a board tape sound? This good.

6) Jethro Tull, "War Child - The 40th Anniversary Theatre Edition" (Chrysalis) Pressed on DVD rather than Blu-ray, Tull's pomp-rock celebration can't claim the "Pure Audio" imprint, but has high-res (96/24) DTS Surround and LPCM Stereo tracks, newly remixed by Steven Wilson. Elaborate 2DVD/2CD set boasts lotsa extras.
