I like all kinds of music. Very fond of lots of metal. My brother is a full on headbanger! He's a drummer and was in an Iron Maiden tribute band named Total Eclipse not too long ago. He can play ALL that stuff in his sleep! I got turned onto Iron Maiden about the mid 80's. Saw them at Desert Sky or Cricket or whatever its called now about 10 or 15 years ago. Somewhere Back in Time Tour if I remember right. Epic!!!
I wish I had my stack of ticket stubs with me to help me out but lets say I've seen a BUNCH of concerts. First concert I can remember going to was Jazz legend Buddy Rich with my Dad and brother at like age 5. Most recently Willie Nelson. I've seen everything from Punk to Reggae, Metal to Country and everything in between. Not too much into the more recent R&B or rap music but the old Motown stuff is really great.
Notable artists/bands I've seen, certainly not even close to all:
Metal/Rock: Cinderella/David Lee Roth (12 or 13 years old, Veterans Coliseum, first real rock concert, Steve Vai on lead guitar, my ears rang for days!), Motley Crue/LA Guns (Veterans Coliseum, Girls, Girls, Girls tour, 87?), Metallica (in the brand spanking new America West Arena, 1992), Iron Maiden, Judas Priest, Motorhead, Soundgarden, Alice In Chains, Dio with Heaven and heck, Primus
Reggae: Steel Pulse, Eek A Mouse, Black Uhuru, Don Carlos, Bunny Wailer, Gregory Isaacs, Ziggy Marley (Paradise Casino, Winterhaven CA), Bad Brains (punk?), Culture
Classic Rock: Bob Dylan, Grateful Dead (15 times in 3 years), Santana, Allman Brothers Band, Tom Petty and the Heartbreakers (the last tour, Red Rocks CO), Fleetwood Mac, Dave Matthews Band, Steve Miller Band, Phish, Black Crowes, Joe Walsh, Blues Traveler, Widespread Panic
Popular: Beastie Boys (TCC Old Exhibition Hall and Compton Terrace), 311/Cypress Hill, Run DMC (UofA mall Spring Fling 1998), U2 (ASU Stadium 1992), Sting (Opened for the Grateful Dead, 1993 Las Vegas Silverbowl), Depeche Mode, Counting Crowes, INXS (Steel Pulse opened, 1988? Compton Terrace)
Country/Western/Bluegrass: George Jones, Willie Nelson, Merle Haggard, Asleep at the Wheel, Old Crow Medicine Show (Mesa Amphi, Grand Old Opry, Red Rocks), The Devil Makes 3, George Strait, Montgomery and Gentry, Craig Morgan (Yuma Co Fairgrounds), Brooks and Dunn, Gary Allen, Alan Jackson, Eric Church, Randy Rogers Band (Yuma County Fair), Bobby Osborne, Dwight Yoakam, Dierks Bentley, Dale Watson, Justin Moore, Chris Stapleton. We have tickets to see Billy Currington in a few weeks.
A little off topic but a number of these artists passed away shortly after I saw them perform. Jerry Garcia died in 1995 a few months after the last concert I saw him perform with the Dead in Las Vegas. Tom Petty died two years ago about 2 or 3 months after I saw him and Joe Walsh at the Red Rocks. Troy Gentry died about 6 months after I saw them at the Grizzly Rose in Denver. I think I am done seeing Willie. I really regret not seeing Randy Travis perform locally, a few months after his last concert in the area he had the major stroke or whatever happened. Now when stuff comes up, we just buy the tickets and go. Life is too short to not enjoy it.
