You Guy's ever heard of Alex Lifeson from the band Rush? he wrote the solo for La Villa Strangiato in 1979, which I think was before E V Halen. O.k there's no tapping in it but I think it's the greatest electric guitar solo ever written and I'm not sure how ground breaking eruption is in view of this, I've love Lifeson's playing since i was 5 and at 23 I still think he was the best even though his lutput of material at tat level is very small compared to for instance EVH, Malmsteem or Satch,.
