#6 (already identified) is great, wonderful horn voicings which dynamically interact with the rhythm so nicely. I like the Miles Davis/Gil Evans version of this which never got onto one of the studio albums of the period (available as a CD bonus cut in a few different sets).
#11 is also really nice, I should probably be placing it, Sounds like Mal Waldron on piano and Booker Ervin on tenor. Probably some old Prestige album I have on the shelves somewhere and should listen to more. Digging the drummer for sure.
