No. There's soprano on Horn Culture and Next Album, the latter featuring a memorable version of "Poinciana" on soprano, along with David Lee's still-mind-boggling cymbal work.
I agree, it's a good album, but I don't think that Sonny plays as freely and loosely as his rhythm section does on this one. A pleasant but ultimately frustrating listen for me, as were/are so many of the Milestones. But if I don't think about it too hard, that's not too big of a problem.
