"I forgot to mention Zappa. I have a few of his LP's -- Sheikh Yerbouti and Apostrophe come to mind -- but my collection's not very deep. I sometimes have trouble getting past the 8th grade potty humor on those lp's, but the musicianship and creativity are undeniably brilliant."
Yellow Snow was pretty innovative potty humor back when Apostrophe was released. :-)
ZAppa was very talented and innovative in certain ways, especially rhythmic patterns, and also an excellent guitarist usually with excellent musicians, but also all over the place.
