Eugene Zador's delightful concerto for the accordion - which he called an 'underprivileged' instrument - is tonal, but coloured by a communicative, contemporary vocabulary, and he finds glorious sonority and colour in the Suite for Brass Instruments. The evocative smaller pieces have been arranged by Mariusz Smolij, as has the characterful and wide-ranging Piano Quintet of 1933, all heard here in world premiere recordings.
