Cold War Kids put on a good show at their ACL Fest debut, they seem to have cleaned up quite a bit since the last time I saw them. They showered, shaved, and even wore clean clothes. Good thing, they played during what felt like the hottest part of the entire festival. The first time I saw them was at an indoor show at Stubb's sometime during the Spring of 2006, so they've come a long way.
Here's a live CWK performance from earlier this year at La Cigale that was broadcast on French radio. Good quality, and the DJ only interrupts for a couple of voice-overs between songs. They will make a return to this venue in November, so I guess they enjoyed themselves the first time around.
