I only caught the last song of JD King, and while it isn't exactly my kind of music I wasn't entirely impressed either. I'm not going to say he's no good, because I can't base it all on the last 3/4's of one song. That being said... thenewno2 was awful. They sounded like a really bad version of Radiohead. If I wouldn't have lost my place on the balcony, I would've left during their entire set. Nothing redeeming in their performance.
Pete Yorn, however, was fantastic. I always appreciate it when a live show is just as good or better than the studio material, and this was certainly the case. Excellent show, great song selection, and good energy. I can't wait for him to come back to the Del Mar Racetrack so I can catch the show again. Definitely worth seeing.
