Music Notes: Live Deerhunter Webcast Tonight, Pete Yorn on Leno, Imperial Stars Stop L.A. Traffic

* Just found out that a Deerhunter show will be webcast live by NPR Music tonight, Oct. 12th. The show is set to begin at 10 p.m. Eastern time.

* Pete Yorn will be on The Tonight Show with Jay Leno Tuesday, Oct. 12th. And he's got a new video out, for his song "Sans Fear" (above).

* The Orange County hip-hop band Imperial Stars stopped traffic on an L.A. freeway this morning, and got arrested for it. The band played songs on a truck that was parked to block most of the 101 freeway in Hollywood. The stunt was apparently a promotional effort for the Imperial Stars song "Traffic Jam 101."

* Heard about this cool video on Twitter called "The Johnny Cash Project": a "global collective art project" that provides assembles countless user-created images for a visual backdrop for Cash's song "Ain't No Grave." And the creators encourage viewers to add their own contributions. It's hard to describe; check it out for yourself.
