All the music that appears in the film Rodents of Unusual Size was created especially for it with Michot composing 22 pieces, 21 new originals, primarily instrumentals, while a "Cajun Bounce" track was written by Bryan Webre. All selections were performed by the Lost Bayou Ramblers, and the score was engineered by Kirkland Middleton at WixMix productions in New Orleans, with additional engineering by Mark Bingham at Nina Highway in Henderson, and by Tony Daigle at Electric Comoland in Lafayette, Louisiana.
