The works of Samuel Adler - born in Mannheim in 1928 but long since one of the leading figures of American music - are both modern and approachable: the blend an edgy angularity with long flights of lyrical melody, and are often informed with both a buoyant charge of energy and an impish sense of humour. This conspectus of his chamber and instrumental music covers almost sixty years of his activity as a composer and thus presents a kind of portrait in sound.
