Probably a tie up between spitz, Versailles and L'arc en ciel. All of them for the vocals, as I am a vocalist myself. spitz is very nice and laid back alternative rock group with smooth vocals. L'arc en ciel is one of the greatest Jrock bands of all time, and I model my vocals somewhat off of Hyde (the lead singer). And Versailles, the best Powermetal band in the world until the split (making me die inside :<) Kamijo (the lead singer) is also an inspiration for my voice. Voices are what stick out to me most in music, so that's why I like those groups. Now that Kamijo is single, I'd that say KAMIJO is my favorite of all time.
