Naxos’ exciting and important American Classics series now includes music of the present day, in this case three recent works by Philip Glass. The Violin Concerto, a work that (surprisingly) adheres to classical conventions, lures us in with beautiful, seductive harmonies. Glass relies both on his trademark arpeggiated technique (sounding in the first movement somewhat like Vivaldi’s “Winter” concerto) and on his favorite harmonic progressions to suggest a sustained melodic line. In the first two movements Glass’ carefully timed harmonic and rhythmic shifts keep you in a happy daze. He breaks the mood in the finale, however, leaving the soloist to practice arpeggios at length until the quiet, serene coda steals in. Adele Anthony, who plays with the kind of skill and grace we would expect in a Mozart concerto, brings off Glass’ work with consummate, convincing musicianship. Company (music for Becket’s prose) for string orchestra is in four movements, characterized by stimulating changes in time signature and rhythm.
