Duke Ellington at the Cotton Club (Storyville, two CDs). This hugely important release contains cleaned-up transfers of all surviving radio broadcasts made by Ellington between 1937 and 1939. Most of them have circulated for years, but this is the first time that they’ve ever been made available in a single package. Listening to these performances is like spending a blissful evening in the Wayback Machine. First-class liner notes by Andrew Homzy (TT).
