Off the top of my head, some stand-outs that might have been representative of the label's different interests.
Golden Circle
Out to Lunch!
The Last Session
Indestructible!
Street of Dreams
Sonny Clark Trio or Horace Silver Trio or Herbie Nichols Trio (I would have a tough time choosing between these, but I would end up on Nichols)
Fats Navarro and Tadd Dameron: The Complete Blue Note and Capitol Recordings
There is such a range of music to choose from. Maybe a good point to try to make, since Blue Note seems to be so identified with HARD BOP and the Jazz Messengers style of music.
in that case, maybe one of the last Wayne Shorter sessions... Moto Grosso Feio, Supernova, Odyssey of Iska?
