Example Input: This is a front to back cd which is a rarity. Kershaw puts together intelligent, thought-provoking lyrics with layered music that always has a lot going on.His creativity in terms of sounds that he comes up with is incredible. One can hear a little radiohead influence on this album.His transition from 80's alterna-pop to his now contemporary 90's acoustic-based sound seems so natural and is actually an improvement on his earlier stuff. I can't wait to hear what he comes up with next.
Example Output:
Positive
