Located my copy of Oscar Peterson "In Transition". The 1st half of the 2 record set is a live 1965 recording at the Trivoli Gardens in Denmark. It is a mono recording and some times the piano is poorly recorded and breaks up or slurs. It is however an awesome display of the trio with Ray Brown on bass and Ed Thigpen on drums. Great music, OK recording.
The second half is a new trio with Louis Hayes replacing Mr. Thigpen, later in 1965 in the studio. Much better recording. I hear no problems with the piano but the music is more controlled, not as powerful a recording. Still great though.
So I can see if the OP just listened to the live side he may hear problems with the piano.
Btw, this is an Emarcy reissue of the two dates. Anyone with the original feel free to comment on what they hear. That would be interesting.
Could not find the "Rare Moods" at this time. I am not very organized.
