The three Berlin-based musicians of the group RAG DOLL—Käthe von T. (vocals), Ulrikke Hanspach-Torkildsen (trombone/vocals), and Amy Protscher (piano/vocals/percussion)—captivate their audience body and soul, taking them on a journey to the golden age of ragtime, boogie-woogie, Harlem stride, and barrelhouse. The spark ignites immediately, and they transform every stage into a magnificent old juke joint in the American South of the 1920s. And as is customary in places like these: you’re welcome to listen, swing, and dance until the air is electric. Welcome to the Roaring Twenties!
