Here's the distributor's review..

This release contains a complete previously unissued concert by the 1966 Miles Davis Quintet. Recorded at the impressing Oriental Theatre in Portland shortly before it was demolished, it presents the only existing testimony of bassist Richard Davis playing with Miles.

Among its many highlights are many great trumpet solos by Miles, including his only existing version of "Who Can I Turn To ?" a free jazzoriented So What, and a beautiful reading of My Funny Valentine.
