Recently I discovered a very interesting blog by Brian Mangum called Three Perfect Minutes. (Edit: Removed the link, the website seems to be offline)
Especially as a Swing music fan and dancer you might be interested in this blog as well.
On a regular basis, Brian is writing about what he is considering as Milestone Recordings in American History.
His latest post from November 28th for example is about trombonist and bandleader Glenn Miller.
Brian gives us a short biography about the artist and features three records from 1939 with additional informations: «Little Brown Jug», «In The Mood» and «Moonlight Serenade».
To enhance the experience, he suggests additional tracks to explore.
