Here's something interesting written recently by Luigi Patiil on REH video comments :
"people don't understand this style, mainly because of their musical ignorance, especially music theory.....what this really is, is jazz guitar played very fast with distortion. Think more Shawn Lane than Paul Gilbert. Vinnie doesn't use common formulas like straight pentatonics, etc...and he makes it very clear at the start of the video. It's all licks played on extended or altered chords, he fused jazz guitar with shred and metal guitar, which is why it sounds weird to people who don't listen to jazz. You might not like his style, but the guy is master of the fretboard. Not everybody follows the beaten path. If you hear someone like the composer Arnold Schoenberg, you probably won't like it. But just because you don't like it and don't understand it, can't say that it's trash. These things are acquired tastes. The only weak point I see in Vinnie's otherwise excellent mastery of the fretboard, is his obsession with speed. He's hardly the only one with that obsession..... 98 per cent of all guitarists have the same problem.
The other problem is that, at the time, every ignorant and idiotic 'critic' was saying of anybody who played metal guitar fast, that they all ripped off Malmsteen, which is obviously false.....Malmsteen didn't invent anything, what he did was taking what was already there, and putting it in a heavy metal contest....if you hear the album 'Tour de Force' by Al Di Meola, you'll see very easily what I mean, as Di Meola was doing it before everyone else. The album was released in 1982, and he had been shredding for years before, so you can safely bet your guitar on the fact that it was really Di Meola who, without intention, started the 'shred guitar' style. Because of the stupid critics who then said that every other shred player copied Malmsteen, players like Vincent who still wanted to play in a 'shred' style, tried to differentiate their playing in other ways, as Vinnie did. I also bet that Allan Holdsworth was a very strong influence on him, although the sound is very different. So there you have it. It all makes sense.....if you know what you are talking about. The majority of people, don't"
