Out to Lunch! was Eric Dolphy's only recording for Blue Note Records as a leader and was originally issued as BLP 4163 and BST 84163. Today it is generally considered one of the finest albums in the label's history, as well as one of the high points in 1960s jazz avant garde and in Dolphy's discography.[citation needed] Tony Williams had turned eighteen a few months (75 days) before this recording, and is listed as "Anthony Williams" on the album cover. A few months after recording this album, Dolphy went on a European tour with Charles Mingus. He died shortly thereafter of a diabetic coma.
