After Passing Ships (interesting album in that it had me wondering if the title referenced some other players that Hill was listening to. For example, the title track sounds a bit like Sun Ra, Plantation Bag seemed to have SGQ influence, and Noon Tide was Horace Silver-ish. Maybe it was just my brain making tenuous connections, but great album regardless).
Anyway, Herbie doesn't show up on this one until the 3rd track as I think the opener was a trio (or quartet if both Rivers & Shorter were playing) while the second track is a solo.
