Cold War Kids’ new EP “Behave Yourself” was released for download on iTunes in December 2009 with a physical album in mid-January, but beyond that there isn’t much else to announce. This is the ninth EP for the group, and the four-track set released at number 177 on the Billboard 200 Chart.

The EP is said to be a collection of songs recorded after the second album “Loyalty to Loyalty” in 2008 that didn’t quite fit with past EPs and albums. This could explain a slight lack of cohesion between tracks. The album takes a few listens to really understand and get into, but after that CWK fans might find a couple new favorites.

“Audience,” “Sermons”—originally recorded on the second EP—and “With Our Wallets Full” are worth the buy. However, the other tracks, “Coffee Spoon” and “Santa Ana Winds,” might take some more time to appreciate.

Perhaps the EP is just too short to judge definitively. The good news is that CWK is rumored to be back in the studio this month with plans for a third full-length album. Until then, “Behave Yourself” will have to tide fans over.
