First and only time I've ever really heard Yngwie Malmsteen, because back in the 80's and after I never really had any interest in so-called Bach-rock as described by my college roommate/guitar teacher:
I went to Generation Axe with my cousin at Westbury. It was a great show... right up until Malmsteen got up there to do his solo thing... and it was the worst thing I've ever heard, period. I'd rather go back to Bogue Sound and stand next to hovering Harriers. Total torture. I decided to go take a leak and get a beer, and apparently so did the rest of the audience because I got on line for the toilet when it was only 10 deep and looked behind me and there was literally half of everyone else. I got back to my seat to clench my teeth for the rest of whatever the hell was going on onstage (it seemed like forever because it appeared to just be the same trash over and over and over again). Awful tone, sloppy playing, nothing interesting about anything he was doing musically.
At the end they all jammed on Highway Star which was great, except for Yngwie's step out solo sections. It was just noise. Tosin Abasi was many orders of magnitude better and that tune is definitely not his genre, but he's a genius, and he really did some cool stuff with his sections.
Marty Friedman did the same thing to my ears at the Baltimore Soundstage not to long ago, too. They came out after Covet and a few other bands and did this intro screeching thing that had no reason to it. It was like a series of song endings that just repeated over and over again with no point - and his tone was just plain awful. I left 10 minutes into whatever the hell it was, so I couldn't tell you what the rest of the set was like. His bass player, Kiyoshi Manii was very entertaining to watch (I was on the right side of the stage, fortunately), but I'm a guy that likes the female bassist trope anyway, so...). Unfortunately, she wasn't enough to keep me from wanting to beat the traffic. When Baltimore Soundstage and Ran's Head Live finish up at the same time on a Friday or Saturday night it can slow down getting out of town and heading back to PA where I lived.
Seriously the most unmusical shit I've ever heard in both cases.
So, how's that for a review?
