The Hot Sardines were "founded in 2011 by Elizabeth Bougerol and Evan Palazzo over a mutual love of Fats Waller." They got their start at underground parties in Brooklyn, and have since toured worldwide with their brand of "reinvigorated classic jazz." Fats Waller covers are at the bottom of the post.
