Every year since 1987, there's been A Very Special Christmas record of one sort or another, the proceeds of which go to the Special Olympics. This year's A Very Special Acoustic Christmas is as great as any previous year's efforts, even though it's deliciously unplugged. Country music superstars like Reba McEntire, Alan Jackson, and Wynonna are balanced by such legendary country and bluegrass figures as Earl Scruggs, Ralph Stanley, Ricky Skaggs, and Willie Nelson (doing a version of Charles Brown's "Please Come Home for Christmas" that's almost as haunting as Brown's). Throw in the father of newgrass Sam Bush's sparkling "Let it Snow! Let It Snow! Let It Snow!," Tift Merritt's sensual "I'll Be Home for Christmas," and a handful of other luminaries and you get a 16-tune acoustic set long on value that ends with multi-Grammy-winner Norah Jones singing "Peace." --Martin Keller
