WLD, too right. Eddie van Halen may have invented tapping, but it was Eric Roche and Michael Hedges who made it more than just an electric guitar solo technique. I guess the key is that for both, it's part of a style which is inherently percussive, so the technique fits in seemlessly.

Thanks for all the vids of Eric. I searched YouTube last year for stuff, but there didn't seem to be anything - looks like people have added more since then. I may just have to get that DVD!
