Les Frères Méduses — Benoit Albert of France and Randall Avers of Norway and the US — return to Austin for ACG's International Series for a performance that follows their triumphant original film score premiere of The Unknown during ACG's 2012 Summer Series. The concert also features the world premiere of "Memoria" by ACG Composer-in-Residence Joseph V. Williams II, which is the first of several major new works Williams will produce this year.
