Hayseed Dixie has made a successful career of refashioning rock and heavy metal classics into bluegrass workouts. The joke is still funny on their fourth studio album, but it's beginning to wear a little thin—the '70s warhorses from Led Zeppelin and AC/DC aren't as entertaining as past efforts, although the version of Green Day's recent antiwar hit "Holiday" is at least slightly nervy. A Hot Piece also finds Hayseed offering up a few originals, although most listeners will continue to be lured by the prospect of hearing metal slabs like Motorhead's "Ace of Spades" served up bluegrass-style.
