'Heavy Timbre' is a reissue of some of the best solo Boogie Woogie and Blues piano recordings to date. Captured for posterity are five legendary pianists recorded at a 'studio party' in 1976, where the challenge of having to play in front of one another clearly brought out the best in each player. This reissue also features five bonus tracks that were not included on the original LP, including a special Sunnyland Slim and Blind John Davis duet and back-and-forth banter that takes the listener right inside the moment.
