Well, here's the 40 year-old dude rambling on again... but I have to say something about Heaven and Hell.
Now, I've seen quite a lot of rock and metal shows over the last 27 years, and many bands I've seen quite a few times. There has been Slayer, Rolling Stones, Merciful Fate, King Diamond, Skid Row, Sebastian Bach, Iron Maiden, Bruce Dickinson, Deep Purple, Ian Gillan, Exodus, Metallica, W.A.S.P., Anthax, Great White, Judas Priest, The Who, Metal Church, April Wine, Motorhead, Dio, Nirvana, Whitesnake, Stone Sour, Aerosmith, Down, Rob Zombie, Alice Cooper, Ramones, Soundgarden, Grim Reaper, Krokus, Robert Plant, Sword, Gary Moore, Disturbed, Rainbow, Anvil, Bullet for My Valentine, Velvet Revolver, Guns & Roses, L.A. Guns, Badlands, AC/DC, Pink Floyd, Scrape, Static-X, Rush, Yngwie Malmsteen, Living Color, Ten Years After, Godsmack, Twister Sister, Nazareth, Meat Puppets, Joe Satriani, The Cult, Blue Oyster Cult, Scorpions, Biff Naked, Voivod, Tea Party, Accept, Finger Eleven, Motley Crue, Drowning Pool, Megadeth, David Lee Roth, Van Halen, Van Hagar, ZZ Top, Saxon, a half-dozen dead blues guitarists, Sabbath with 5 different singers, all the other Ozzfest bands, plus too many I've forgotten. I've seen Ozzy the most - 24 times, including six times with Sabbath.
This year, I went to see Heaven and Hell three times (Montreal, Quebec City and Ottawa). It is THE BEST performance I have seen in my life! Screw the one-dimentional Dio-bashers and decide for yourself. Go see this show!
