one of my college roomates turned me onto his bass playing--esp. since paul kosoff was such a minimimalist fraser really was playing four-string lead most of the time. his career post-free wasn't that notable, buy i musta listened to "fire and water" a thousand times.
Sorry to hear this. Andy Fraser was one of my favorite bassist, and believe it or not, Peter Cetera said Andy was one of his main influences.. If you ever get a chance, listen to them and compare, you will hear Andy's style in Peter's bass playing.
