Technically the best Guitarist on the planet, Vai has a weird sense of humor which largely seems to be influenced by his previous work with Frank Zappa. His music varies widely from very soulful melodic peices to work with absolutely no melody, which just riff around a central idea. His varied style makes him a wonderful musician to listen to. He has numerous cds including Sex and Religion, Passion and Warfare, The Ultra Zone, Fire Garden, Alien Love Secrets, and more.
