This set is extraordinary.Of course,the sound quality is not hi-fi,but it's very acceptable for a live recording of the war days.But more than this,like Duke's magnificent live recording in Fargo,1940,this concert includes some of the greatest music ever played.First, a look on the players: Rex Stewart,Shorty Baker,Wallace Jones,Ray Nance,trumpets;Lawrence Brown,Juan Tizol,Tricky Sam Nanton,trombone;Johnny Hodges,Harry Carney,Ben Webster,Otto Hardwicke,Chauncey Haughton,saxes;Fred Guy,guitar;Junior Raglin,bass;Sonny Greer,drums;Betty Roché,vocals;and of course,Duke on piano.The highlights ? All the tunes! But mostly,and incredible,more than six minutes long version of the old "Black and tan fantasy",with superlative playing by Hodges (did he ever played something that wasn't superlative?),great,very great growl and muted trombone by Sam Nanton (1904-1946),maybe the greatest master on this very difficult instrument;listen to his almost human voice when he plays trombone;this is truly overwhelming.Nobody never played trombone that way."Moon mist",a Billy Strayhorn (1919-1967) original,is a perfect vehicle for the violin of Ray Nance (1913-1976)."Jumping punkins" features Sonny Greer,Duke's greater drummer with Sam Woodyard (1925-1988).Then,the portraits: "Portrait of Bert Williams",featuring Sam Nanton in another extraordinary wah-wah intervention;"Portrait of Bojangles",one of the immense masterpieces from 1940,with a furious tenor sax solo by Ben Webster(1909-1973),maybe one of the greatest things ever blown;"Portrait of Florence Mills",aka "Black beauty",features the underrated Shorty Baker.Then comes THE masterpiece,the tune that will urge you to buy the set: "Koko",another 1940 gem.Don't miss it,this is one of a handful of masterpieces in the history of jazz.Nanton is sublime,and the arrangement is completly out of this world.Two minutes and twenty seconds of pure madness.I really wonder who many hours it took them to rehearse this amazing,short piece of music."Stomp",or "Johnny come lately",is a very difficult composition by Strayhorn,with great band playing."Black,brown and beige",an almost 50 minutes long suite,is a masterpiece which was very rarely played by Duke's band.It features,among others,some unreal playing by Sam Nanton.Then,another gem from 1940,"Jack the bear" and "Cotton tail",played at an incredible tempo by Ben Webster.The relaxed an melancholic "Day dream",in which Johnny Hodges swings one of the greatest things ever played on alto sax;"Boy meets horn",featuring Rex Stewart (1907-1967),another underrated master.And finally,"Mood indigo",one of the most beautiful tunes ever composed.Please,don't miss this very important concert,because it includes some of the greatest things ever played.Just forget the sound quality (which is not so bad),and let Duke's band seduce you .
