The genius of the late Norman Granz lives on in this two-disk DVD showing some of the greats of jazz performing and relaxing in the 1950s, '60s and '70s. You'll want to see everything on both DVDs, but the real gems are five tunes featuring alto saxman Charlie Parker, pianist Hank Jones, drummer Buddy Rich, bassist Ray Brown, tenor saxmen Lester Young and Flip Phillips, and trombonist Bill Harris in a 1950 session, plus a reissue of "Jammin' the Blues," Granz's 1944 Oscar-nominated movie short featuring Young, Harry "Sweets" Edison, Illinois Jacquet, Barney Kessel, Jo Jones, Sid Catlett, Red Callender and others. That's not to say the 1966 Duke Ellington trio session, two tunes apiece in 1979 from guitarist Joe Pass and singer Ella Fitzgerald, and 1977 Montreux Jazz Festival sessions featuring Oscar Peterson, Count Basie, Benny Carter, Dizzy Gillespie, Clark Terry, Vic Dickenson, Al Grey, Eddie "Lockjaw" Davis and other stars aren't also good. They are, and you'll want to view all of these several times. Other features like Nat Hentoff's portrait of Granz, Granz's introduction, still photos and silent footage from the jam sessions, jazz portraits by artist David Stone Martin, and interviews with Jones, Edison, Terry, Jay McShann, Phil Woods, Ira Gitler, James Moody, Slide Hampton, Roy Haynes and Jimmy Heath are all fine additions. But the music, appropriately, is the biggest part of these DVDs. It will take you more than three hours to experience it all, but the time will be very well spent. You'll be grateful that Granz collected and preserved these bits of history during his career and that Laser Swing Productions and Eagle Eye Media have put it all together on DVD.
