With his slow-moving, understated music, David Daniell makes a fine spokesman for the notion that anything worth doing is worth doing for a long, long time. Whether he's contributing moody strums and sculpted E-Bow drones to the guitar trio San Agustin or stringing computer-generated pings and bumps across gulfs of silence on Sem, his solo debut on his own Antiopic label, he develops his material patiently, the better to let you observe the sounds from every angle.
