Crystal Bowersox playing with accompaniment from John Popper. Bowersox sings nice and strong, don’t she? Popper’s playing on this piece is very interesting stuff, plenty of colorful accompaniment, and a solo that seems more like free jazz than R&B. He pulls it together by the end, but at least some of the time I wondered what the solo had to do with the song. That said, there is no one else in the world who plays like this, and it’s obviously something you’ve got to think about to do it, so I’m listening carefully.
