Bringing a little bit of the Big Easy to the Brew City, this relatively new but red-hot band, The Sweet Sheiks, is a toe-tapping quintet inspired by the popular jazz and blues music of the tens, twenties, and thirties. Led by the soulful and sultry vocals of Jen Müttin-Schrank (guitar/saw/washboard), the rest of the charming and talented band includes Ousia Lydian on vocals and violin, Garrett Burton on banjo, Andrew Spadafora on clarinet, and Aaron Johnson on tuba. Sweet Sheiks’ acoustic stylings are compelling, diverting, and are best summed up in two words, “refreshingly vintage.”
