For me, any discussion regarding jazz begins and ends with the greatest jazz pianist (...no, make that the greatest pianist of the 20th century), the genius...Art Tatum. Do yourself a favor and get some of his cd's. Also, you MUST get a copy of the Art Tatum Collection (published by Hal Leonard) which is available at amazon.com. This book contains the piano music of his great performances...believe me, even great pianists like Horowitz and Cziffra have met their match in Tatum's technical facility!! He represents the highest achievement in his field. Regardless of whether one can attain to his level or not, his music making is a source of complete amazement and inspiration.
