A bit ago, I was throwing the kids around in the kiddie pool and the radio played a jazz jam the music students were doing live, on campus. They took "Lowrider" by War and slowed it down slower than a Pink Floyd track and jazzed all over it at like half tempo on an already slow song. It was so moody, cool and unexpected.
No way to describe it, really, but that's why I listen to that station, sometimes. They pop out surprises.
