The are playing Mike Stern's Chromazone from his Time In Place album. Alas, only the bass player solos. Interestingly, he has no insignia on the sleeves of his uniform. A guest perhaps? Let's see if this link works... Link Edit: Link to live performance of Chromazone - it might be Jeff Andrews in the bass chair. Also, I saw more videos of this small group ensemble - none are wearing sleeve insignia on many of these gigs.
