"It Ain't Christmas Without You," Roxy Roca (self-issued)

This eight-piece Austin, Texas soul band puts together a fine old-school holiday tune and backs it up with a cover of "Back Door Santa" to boot. The single is from 2014, although the A-side was available last year on a compilation from Converse. You can also download the A-side, but not the B-side, from Amazon. Both sides are up at Soundcloud if you want a taste. The band sells a physical CD single with a cover that doubles as a Christmas card, so if you act fast you can send a unique (and cheap) present. They even have bulk ordering options.
