Dutch violinist Diamanda La Berge Dramm explores the nature of dance in solo violin music with this bold yet captivating pairing of J.S. Bach and John Cage. The first four movements of Bach’s Partita No. 2 are pure dance, with its “Allemanda,” “Corrente,” “Sarabanda,” and “Giga.” However, its final movement, “Ciaconna,” is something of an anomaly. One of Bach’s most profound statements, it’s brought into the 21st century here with the addition of two female voices, which intone chorale melodies over the intricate solo violin lines. It’s the perfect springboard into US composer John Cage’s enigmatic homage to Erik Satie, Cheap Imitation, a meditative, meandering piece originally written as a piano ballet score. For Cage’s “The Wonderful Widow of Eighteen Springs,” La Berge Dramm puts her bow aside and accompanies a haunting female solo voice with percussive effects played on the body of her violin.
