Seconded, it's an amazing set with relatively excellent sound. It thrashes all other Hawkins collections.
Hans, there was a boxset that came out on Affinity called "The Complete Recordings 1929/1941".
Affinity Boxset
Do you happen to know how it compares with the JSP set in completeness & sound?
Believe it or not, there is not that much overlap between the two sets. The Affinity set releases all known tracks with Coleman Hawkins other than those with Fletcher Henderson during 1929-1941. The Mosaic does not attempt to be comprehensive. Most of the earlier tracks are selected numbers with Fletcher Henderson that have Hawkins solos. None of them are on the Affinity box. The Affinity box includes a number of discs that contain all of Hawkins' European recordings from the 1930s. The Mosaic box contains none of these recordings for copyright reasons. There is a strong overlap on a few discs that contain Hawkins' American 1939-1941 recordings, but the Mosaic also has a good chunk from the later 1940s that is not on the Affinity box. Bottom line: If you like Hawkins and have the Affinity box, you still need the Mosaic. That is even separate from the major improvement in sound quality.
Thanks for that, John but it was a comparison between the Affinity and JSP sets that I was after. It's irrelevant now because I decided to buy a copy of the JSP set, anyway, a few days ago and I'm very happy with it. The remastering sounds terrific.
