Touted as the only all-female accordion ensemble in the Western world, the 18 members… wear their hair in pigtails. The orchestra is the fantasy-made-reality of local accordion impresario and conductor Walter Keuhr. The MSO plays pieces by Schubert, the Beatles and The Kinks, among others. You gotta raise an eyebrow at a man who dreamed of leading a troupe of women in pigtails working a squeeze box. Paging Dr. Freud.
