Following on the heels of their performance last month on Conan, Louisville’s Houndmouth showed up on the Letterman Show last night and played the crap out of Ludlow from their debut album From The Hills Below The City.  Thankfully the band veered away from their Alabama Shakes-y performance on Conan, sounding on Letterman more like their admitted-influences, The Band.  Houndmouth is out on tour and will be back to Cali in August to play the High Sierra and Outside Lands Festivals.
