About a week ago, PCL LinkDump had a post about some excellent space age lounge music mixes done by Chris at Ultra Swank. They're all I've listened to for the last week (they were the soundtrack of my Wharton and Rosenberg journeys), and all three volumes are good, but the first one is my fave. It's really swingin'. The guys in the Rat Pack might say it's koo-koo. The second is called Space Age Lounge Volume 2 - Red Carpet Ride and the third is Space Age Lounge Volume 3 - Love at First Flight.
"Rio Magic" is representative of what you'll get on Volume 1.
