Alex laiho is the lead guitar for the finnish metal band "Children of bodom' who influenced by many people like Zakk Wylde, yngwie malmsteen and many more. He has developed amazing skills over many techniques and some killer riffs, He's mastered things like artificial aharmonics and whammy bar play, to me and many more this guy ranks up there with people like malmsteen and paul gilbert.
here's a vid with some of the riffs/solos he can do
