I found this page on WFMU’s beware of the blog featuring 42 different versions of Earle Hagen’s classic composition harlem Nocturne. For all of the hundreds (thousands?) of times I have heard the piece it has still never failed to elicit a sense of mystery and danger.
From the post, which was made in 2008 in honor of Earle Hagen’s death:
Hagen is also the composer behind “Harlem Nocturne”, probably one of the most covered saxaphone songs in history (500 versions so far and counting). Writen in 1939 while Hagen was an arranger with the Ray Noble Orchestra, the song has lived on as a standard for every big band, bar band, R&B band, and instrumental band since. It is also of course a crime soundtrack staple.
