Only the once. Hammersmith Palais 1981, but it was and remains the best gig of my life.
Because this forum is full of rockists, I went for Kraftwerk as they kicked the whole thing off. I could defiantly make a case for Sir Frankie Knuckles, Richie Hawtin/Plasticman & Aphex Twin.
The Smiths, or at least that's who a lot of bands said they were influenced by....Great band.
BUDDY HOLLY - without him no Beatles, no Stones, no Oasis, oh the list just goes on and on and yeah !
