During four marathon recording sessions in 1953-55, Norman Granz recorded Art Tatum playing 119 standards, enough music for a dozen LPs. The results have been recently reissued separately on eight CDs and on this very full seven-CD box set. Frankly, Tatum did no real advance preparation for this massive project, sticking mosty to concise melodic variations of standards, some of them virtual set pieces formed over the past two decades. Since there are few uptempo performances, the music in this series has a certain sameness after awhile but, heard in small doses, it is quite enjoyable. A special bonus on this box (and not on the individual volumes) are four numbers taken from a 1956 Hollywood Bowl concert.
