One of my favorite YouTubers out there is Mr. Andy Rehfeldt. You may not know his name, but you've probably heard his music.

He's a behind-the-scenes composer in L.A., but his best work is what he puts up on YouTube!

He does crazy versions of songs, and syncs them with live videos of performances from whatever band or singer he's making the parody of.

If it's a metal band, he'll do a polka, reggae, or Radio Disney version of their song. Like this amazing version of Slayer's "Angel of Death", Radio Disney style!

If the artist is a pop musician, he'll do an even more amazing metal or death metal version of the song, either using their original vocals or putting death growls on it. Like this:

I love this guy's channel. If you have a bit of time, check him out and enjoy!
