As far as their influences, there seems to be no end to the list of names and genres that influence their sound. Whether they are performing dyed-in-wool bluegrass as a classic country standard, the Mules carry a pack of influences and styles that would, well, weigh down any pack mule.
“We love Monroe, Crowe, Rice, Twitty, Wiseman, Robbins, DLQ, the Osborne Brothers, Seldom Scene, the Gentlemen, and even pre-turn of the century,” Shifflett listed off as their most admired musicians and style. “We also love great harmonies and frequently switch parts for fun.”
Nailing down a favorite song to perform is also challenging, but “Sweet Sunny South” is a lyrical favorite for the Mules, who deliver high energy and humor during their sets and invite friends to play, such as Bob Minner, an acoustic guitarist in Tim McGraw’s band. “Marty Robbins’ ‘Big Iron’ is a much-loved story tune and so is ‘30 Years of Farming,’” he said. “Instrumentally, ‘Foggy Mountain Special’ gives everyone a chance to shine, but ‘Wheel Hoss’ is a big crowd pleaser and a real barn burner!”
