If you dig "Peace" you'll probably dig "Shirl," a Horace Silver ballad with a couple of rhythmic quirks and a handful of far out harmonic ideas.
James Mahone has provided a transcription of the head. I'm trying to spell out the chords (or implications of chords, you know) and either make a usable lead sheet or just learn the tune so I don't need one. At this point it seems rather doable on guitar. I know Hutcherson did a version on vibes (with strings, no kidding). If anybody knows of a version done on a horn I'd love to hear it. And, incidentally, I think Flanagan's version of "Peace" is pretty definitive, but I'm all ears.
