Founded in New Orleans as live music began sprouting from the ashes of the pandemic, Obliquestra features virtuoso fiddler, guitarist, and musical sawist Dr. Sick (of the Squirrel Nut Zippers) accordionist David Symons (of Vermont’s Brass Balagan), and clarinetist Susanne Ortner. Together, with banjoist Aaron Gunn, the band performs a mix of Moldovan klezmer, Brazilian choro, New Orleans jazz, and Russian and French waltzes. Festival of Fools will be Obliquestra’s Vermont debut.
