Richard Barrett Spectrum, an intimate loft turned performance space on the Lower East Side, fosters a sense of immersion in the music being performed, an all-in quality that was rewarded in a tribute in June to this British composer, born in 1959. Featuring chamber works performed by members of the ensemble TILT Brass — in “tendril,” the sound made by rubbing a harp’s strings was doubled by electronic strumming noises; “Equale,” suffused with the sounds of brass instruments, morosely ebbed and flowed — it was an engrossing look at a searching artist. |
