Zakk is an awsome...no waite... a phenomenal player. I also have to agree with Locomotive breath for his reasons that he listed. Also Zakk is awsome in online interviews..uncesored and thinks just like I do. I have everything he ever did with ozzy (bootlegs too), the original limited addition Live and loud video with the grill cover, the dvd version, Pride and Glory (Also makes a great beer coaster),Book of shadows (His acoustic album), BLS albums, Ozzy Live at Budokon both on Cd and dvd, plus his ozzy pick with his name on the back.
I like all of Ozzy's guitarist:
Toni Iomi
Randy Rhoads
Brad Gillis
Jake E. Lee (I have his the ultimate ozzy video, Japanese import live video with ozzy, and his Badlands video)
Zakk Wylde
and Joe Holmes
One of my most prized possessions is a huge Bark at The Moon promo poster signed by all the band members. I have it framed (No it's not for sale) :-)
Hell I even have Ozzy tattooed on my left knuckles wich I did when I was 13 and the same year I started learning guitar. I'm 30 now.
I like both Zakk and Randy equally.
I started learning guitar because of Randy Rhoads..but Yngwie J. Malmsteen is my biggest influence.
