Norman Granz was perhaps best known for the "Jazz at the Philharmonic" or JATP concert series, but in recent years we've been flooded with numerous DVDs of his many productions. Now, a number of his classic video productions have been collected into this two DVD set, Norman Granz Presents Improvisation. The collection includes a variety of settings and groups, including Coleman Hawkins and Charlie Parker from 1950, various performances from the 1977 Montreux Jazz Festival, Duke Ellington at the Cote D'Azur, and as a bonus, the 1944 film titled Jammin' the Blues, featuring such luminaries as Jo Jones, Harry 'Sweets' Edison, Lester Young, and many more in an open jam-session setting. As a fan of jazz history, this is a must-own collection of videos, if only for the Bird and Hawk, but the package as a whole covers a wide range of the jazz history spectrum. You could do a lot worse than starting your jazz DVD collection with this one. Enjoy!
