The critically acclaimed Jack Quartet perform four new works by the Áltavoz Composers, a group of Latin American composers who have emigrated to the U.S. and Europe. Felipe Lara, Jose-Luis Hurtado, Mauricio Pauly and Jorge Villavicencio Grossman are all dynamic compositional voices working in the modernist tradition; their works are heard here in the context of one of the most challenging and revered trajectories of the classical canon, the string quartet repertoire. "explosive virtuosity." (Boston Globe) "viscerally exciting." (New York Times) "thrillingly vital." (New Yorker)
