Contemporary symphonic music tends to fall into either one of two categories: hopelessly cerebral concert hall material that is difficult (if not impossible) to understand - or background music for motion pictures. Neither classification would be much to the liking of New York native Anthony Iannaccone, who sets out to prove that one can have the best of both worlds on LOOKING BACK, MOVING ON. Both his third and fourth symphonies make a strong case: spirited, organically structured, and imaginative, they are formidable displays of American verve. The Concertante for Clarinet and Orchestra, more subtle but no less energetic, drives home the point.
