Corpus Callosum are a seven-piece traveling sideshow. Their music is made using arcane and unusual instruments like wine glasses and Stylophones, and it sways and hums in a style similar to fellow anachronistic acts like Beirut and DeVotchKa. The show is rounded out by their emphasis on performance. Puppets, stilt walking, cardboard sets - it adds up to a dizzying interpretation of a school recital, a talent show, a carnival. Do you ever see those vouchers with the elephants and clowns and red balls adorned with stars and regret always missing the circus when it unceremoniously blows through town? Here is your chance to experience that eerie magic before Corpus Callosum pack it in and leave for yet another town, more eyes and ears to be met with wonder.
