HOUSTON’S NEW-MUSIC stalwarts Aperio, Music of the Americas distinguished itself in its early years by tracking down and performing the music of North Central and South American composers who engaged in musical dialogue across and beyond their respective geographies. Now in its 18th season, Aperio continues that spirit of innovation and cross-cultural conversation with Strings and Hammers, a concert of contemporary and modern music by Latin American composers for various and unusual combinations of (unplugged) guitar, violin, cello, and piano. Strings and Hammers takes place on Jan. 26 at Midtown Arts and Theater Center Houston (MATCH). If you love the classical guitar, this is a can’t-miss concert.
