From Style Weekly:

[Susan Greenbaum] and lead screamer of Lamb of God are planning a duet on Greenbaum’s Christmas album. The two met while Greenbaum was recording the album at Sound of Music Studios at Third and Broad streets. She was working on her project downstairs and Blythe was doing preproduction work on the upcoming Lamb of God album upstairs.

“I have a very nice baritone voice, so I said I wanted to sing a duet with her,” says Blythe, who calls the project “just weird enough for me.”

For Blythe and guitarist Mark Morton, who will also play on the track, the collaboration is a hoot. “It’s going to be awesomely retarded, especially since I f—ing hate Christmas and she’s Jewish!” Blythe wrote on his MySpace Web page.

Blythe says he doesn’t know or care what his fans will think. “It’s a fun thing as a musician,” he says.

Jewish folk singer + Randy Blythe + Mark Morton + Christmas = WTF!!?
