I really, really like Nick Pitera. Mahn that guy is talented.
I first heard his Les Miserables cover and was amused by it. I never looked for it again, but I accidentally found his Disney medley and fell in love. Heh, he even sings better than me.
If you've never heard him, go now to YouTube and type him in. I suggest you try his Disney medley first though.
Oh, and to support him, go get his first original song "Better Days" on iTunes. It's really amazing.
