What happens when the vast machinery of the symphony is entrusted to just seven musicians? At first, the idea seems absurd. Strauss’s Till Eulenspiegel was written for one of the largest orchestras of its time; Ravel’s La Valse is an apocalyptic dance that normally takes every inch of a concert stage to contain. Even Prokofiev’s deceptively light Classical Symphony relies on the precision of a full ensemble. How can all that thunder and color possibly fit into the hands of a string quartet, double bass, accordion, and piano? That is precisely the provocation behind Boye’s Café Orchestra’s new album.
