I might be tempted if I could replace the entire Chronicle box with these (and anticipated 1956 set) but starting in 1954 leaves a hole for the 1951-1953 recordings. I do have the Legendary Prestige Quintet Sessions box (pretty much a perfect set) along with the Chronicle box, which covers everything for me with the Quntet box being upgraded duplicates. My ideal would be another 4-CD box covering the sessions not on the Legendary Prestige Quintet Sessions box. They got it right for Coltrane, with the leader, co-leader, and sideman boxes. Those were perfect boxes to me. Fantasy was starting to do great reissue work right before they sold out to Concord.
