Mule is a defunct rock and roll band hailing from lovely southeastern Michigan. With the exception of the Stooges and the MC5, they are the greatest band to come from that region.

Often compared to poseur, Jon Spencer, Mule is actually a ferociously honest blues-rock trio steeped in whiskey and beer.

Comprised of members of Wig and the Laughing Hyenas, they tore early 90s rock a new asshole with such songs as; Hayride, A Hundred Years, and Mississippi Breaks.

Mule recorded two full-length albums; Mule and If I Don't Six and one EP; Wrung, before breaking up to persue other directions.
No not Gov't Mule you stupid fucking hippie...just Mule!
