"Tiny Desk Concerts" are intimate video performances, recorded live in NPR Music's Washington offices. This one, just published last Friday, is by the Preservation Hall Jazz Band; it lasts around 20 minutes.

Per Bob Boilen, at whose desk these events happen: the "Preservation Hall Jazz Band is a hot and historic outfit from New Orleans, and its members brought us a tuba-wielding Santa and some original holiday cheer and praise — what they call a Cajun Christmas from the French Quarter."
