Haven't been to a lot of concerts in recent years. But the best concert I ever attended was Bruce Springsteen 8/23/81 at the L.A. Sports Arena. I became a big fan of The Boss and his music that night, and continues to this day. I've been a big Beatles fan since I was a child, too, and have seen Paul McCartney several times in concert. Most of the acts I've seen are "old school" artists over the years, so I've seen The Who, Heart, The Stones, Paul Simon, Huey Lewis and the News, Alison Moyet, The Monkees, Human Rights Now show (Springsteen, Peter Gabriel, and others), Red Hot Chili Peppers, and a lot more.
