Gastre Del Sol consists primarily of Chicagoans Jim O'Rourke and former Squirrel Bait member David Grubbs. For the better part of the 90s, they've brought avant-garde concepts of experimental sound to a younger, ex-indie rock audience. Camofleur generally mined for experimental sounds, but this time they came from pop and folk. With echoes of Van Dyke Parks and John Fahey, Gastre shifted their focus from sound to arrangement, presenting tunes for the first time. Still, the music defied category, melding piano, acoustic guitar, strings, horns, tape noise, and deadpan da da lyrics into delicately abstract and melodic sound paintings. This is Art music at its most listenable, eluding your grasp rather than testing your patience. --Steve Tignor
