Sound the brass! Copland’s victorious fanfare is a fitting start to an afternoon of contemporary chamber music, featuring Martin Chalifour, Concertmaster of the Los Angeles Philharmonic. Flute, trombone, percussion and piano make an unusual ensemble for Carl Vine’s jagged miniatures. Subtitled “Thirteen Images from the Dark Land,” George Crumb’s Black Angels is a surreal, unhinged look at fallen angels through an amplified string quartet. With movements like ‘Pale Yellow’ and ‘Fiery Red,’ Jennifer Higdon’s Trio asks “can colors actually convey a mood?” Nino Rota, known for his film scores including the haunting theme to The Godfather, took almost three decades to pen his Nonet for wind quintet and strings—a shock when witnessing its spontaneous-sounding joviality.
