Sam Rivers recorded for Blue Note from 1964 to 1967. While recording for Blue Note, he was an avant-garde innovator with an inside/outside hard bop sound. Wrote Steve Huey on Allmusic.com: "[Sam Rivers] took his music as far out as he could while maintaining a recognizable structure; his work fearlessly explored wildly dissonant harmonies and atonality, dense group interaction, cerebral rumination, and passionately intense, free-leaning solos."
Rivers recorded four albums for Blue Note: The classic "Fuchsia Swing Song," the avant-bop masterpiece "Contours," the radical standards album "A New Conception," and the brilliant "Dimensions and Extensions" which also comprised Rivers' half of the split double LP "Involution" with Andrew Hill.
I paraphrased and plagiarized much of this info from Allmusic.com. But WTF? It doesn't really matter. All that matters here is that this is Sam Rivers on Blue Note. Everything else is tiny details.
