Here are a few very early and probably ill-considered comments!
Track 1
From the 50s, let's say about 1954. Bears a strong resemblance to Woody Herman's music of that time, particularly the riffs and the general character of the soloists, but this is a smaller outfit than Woody's orchestra, octet to ten players, perhaps. Relaxed, groovin' - just my sort of jazz.
Track 4
Very much in the tradition of the Hot Club de France. That ought to be Grapelli, but it doesn't sound quite so impeccable as him, so - the master late in his life or a follower closely influenced by him? Tune is "After You've Gone", a Grapelli favourite IIRC.
Track 5
Blues/boogie piano (hope there aren't two!) plus bass and drums. Could be a tack piano. For this sort of thing I think Sammy Price or Jay McShann, but it's probably someone more contemporary.
Track 6
Having wandered through ideas like Goodman and Carnegie Hall Concert, I'm guessing this is Artie Shaw in a 1941 airshot from Hollywood playing "After You've Gone" with sensational, swinging playing from Hot Lips Page and Dave Tough. Excuse me if all this is quite wrong!
Track 7
A real swing-to-bop feel about this one. A band of about seven pieces of the sort that Sir Charles Thompson used to lead, though this isn't him on piano. Date about 1946. Strong "Honeysuckle Rose" resemblances in the boppish theme, so I suppose it's on "H R" changes.
Track 9
Love this one! Again, just my sort of music! 1950s, a blues, swings beautifully. Again a medium sized band, this one including tuba and oboe. Latter made me think of Yusef Lateef, lovely boppish trumpet had me thinking Thad Jones. And do I hear Lucky Thompson? "Arranger's piano" of the sort Mulligan used to play, but I think we're in different company here. Would really like to know what this is!
That will do for now.
