I'm an admirer of so many - Steve Howe, Van H, Brian May, Hendrix, Lifeson, SRV, Joe Walsh, Johnny Winter, Ritchie Blackmoore, Angus Young, David Gilmour (in terms of music that I like) as well as Gordon Lightfoot and Ian Anderson in a different vein.
Slash I appreciate but I'm no G&R fan. If you haven't heard Prince do While My Guitar Gently Weeps at the George Harrison induction to the R&R Hall of Fame in 2004, you've missed out on a real treat.
VH certainly did not invent the hammer technique and I'm glad that he disavowed that.
