In Britain, Christmas records are strictly for the Val Doonican/Cliff Richard end of the market. Yet in America, where they call them “seasonal” albums, even the most credible artists seem moved to sing of those sleigh bells a-ring-a-ding-dinging. Hence gospel veterans the Blind Boys have recruited an impressive cast that includes Richard Thompson and Chrissie Hynde (“In The Bleak Midwinter”), Michael Franti (“The Little Drummer Boy”), George Clinton (“Away In A Manger”) and Shelby Lynne (“The Christmas Song”). Unfortunately, though, a turkey is still a turkey, and the fact that Tom Waits has contributed to the trimmings only makes it more embarrassing. Bah, humbug.
