Anyone who missed the Concert FM's Jazz Profiles radio programme on Duke Ellington a couple of weeks ago -- or if you heard it and want to hear it again, can find at least some of it online here in five short parts (scroll down past some other audio gems to find the shows, or click here for parts one, two, three, four and five) .
As one of the show's interviewees avers, Ellington was unquestionably the greatest composer in the history of jazz. Listen in and find out why.
If you want something further, check out some other NPR Ellington excerpts here, or invest in perhaps the best introduction to Ellington's genius, Beyond Category, or my own favourite his Far East Suite. Superb.
