The Rolling Stones recorded Black and Blue while auditioning Mick Taylor's replacement, so it's unfair to criticize it, really, for being longer on grooves and jams than songs, especially since that's what's good about it…
Essential: a masterpiece of progressive rock music.
I got acquainted by this band a very long time ago. A friend of mine lend me once a CBS compilation called Fill Your Head With Rock in 1971. One song of theirs was featured (I guess that you all can imagine which one).
The opening track In Ancient Days is a mix of psychedelia combined with heavy keys. Invading brass can be heard as well. Such a song might sound outdated but it is always a pleasure to listen to. It is very much in the style available during that period. I quite like the song.
The Complete CBS Buck Clayton Jam Sessions (extremely rare & limited 1993 US 32-track Mosaic audiophile 8-LP box set) is a superlative package contains all the jam session recordings for CBS, plus alternate takes and originals restored to their full length, with soloists including Joe Newman, Ruby Braff, Urbie Green, Coleman Hawkins, Woody Herman & more. Housed in a beautifully presented textured outer black box with front pasted picture cover, complete with an informative 20-page LP sized booklet, featuring stunning black & white session photographs and extensive liner notes).
