Probably the best Christmas compilation to come out this year is In the Christmas Groove, sporting 12 obscure, but very funky x-mas choons. By artists like Milly & Silly, Zebra and Electric Jungle (okay, Jimmy Reed and Harevy Averne are on there as well), and mostly taken from the original vinyl. Here's a great track by Funk Machine.
Funk Machine - Soul Santa
All this funkiness reminded me of a good funky x-mas album by Shawn Lee, featuring a hard hitting sitar-version (!) version of Little Drummer Boy.
