Named for an esoteric California artist who practiced interstellar telepathic communication in an isolated cabin, Grant Wallace Band is weaving a fresh, diaphanous sound from threads of indie rock, experimental jazz, folk and bluegrass. Sprung from Chicago’s new music scene, these conservatory-trained musicians banded together to blend their diverse musical interests and create songs based on folk and jazz streams that maintained both the compositional integrity and eclectic palette they learned in their studies of classical and contemporary music. An extra spark comes from an affinity for outsider artists, including the band’s namesake, a California artist who drew structural diagrams of the universe based on professed telepathic communications with beings from other star systems. Since its debut the band has charmed and surprised Chicago audiences at venues including Uncommon Ground, the Gallery Cabaret, Opera Cabal and Northwestern University. Tickets are $12/advance, $15/at the door.   The UI Opera Studies Forum will present a pre-opera talk on Berlioz's Les Troyens on Thursday, January 3, at 5:30 p.m. in the University Capitol Centre (UCC) Executive Boardroom, Room 2390.

Marvin will guide audiences through the story of Les Troyens (English translation: The Trojans) in preparation for the Metropolitan Opera’s Live in HD theater transmissions of the production, which are shown live at venues worldwide.
