The group is described as a "classical ensemble with a pop mentality". They often perform standing up, regularly playing music from memory without sheet music. Calefax has commissioned over two hundred pieces for reed quintet, which it performs alongside arrangements of preexisting works. Their repertoire spans the entire history of music, including Renaissance music, Baroque music, Impressionism in music and Jazz. wikipedia
