....one of the coolest, yet most difficult things about Yngwie isn't even his blurry speed, it's his seemingly effortless switch from sweeps to alternate picking to insure every note comes through clear...and his timing!...I can play some of his stuff if I organize it in a friendly way...namely, the bridge in "Liar"...those sweeps and such, they're all logical, but when you hear him play them he's adding little notes here and there and essentially you KNOW he's not using strict up down up picking....just going off!
I'm not one to sit down and listen to his stuff lately, but every now and then it's great. I recommend the Trial by Fire...it's great, but I can't make it through the entire CD...just too much for me.
Yngwie is great for practice, and helping you increase your speed. Use it as such and your playing will improve immensely...check out the Anthology tab book if you're really into it..the old Wolf Marshall tabs are pretty close, and it's got all the songs you'll need to cure the fever!
