Booker Ervin’s debut as a leader teamed the intense tenor saxophonist with fellow tenor Zoot Sims (one will have little difficulty telling the cool-toned Zoot apart from Booker), trumpeter {|Tommy Turrentine|}, pianist {|Tommy Flanagan|}, bassist {|George Tucker|} and drummer {|Dannie Richmond|}. Ervin (who has his ballad Largo as a feature) performs five originals and Poor Butterfly; best are the slow blues The Blue Book and the rapid blues The Book Cooks.
