ILWACO, Wash. — Northwest Heritage Resources, in partnership with the Columbia Pacific Heritage Museum, presents a concert performance by traditional musical group Sin Fronteras. The concert is scheduled for 7 p.m. Saturday, April 30 at the museum, located at 115 S.E. Lake St.

At a time in the Pacific Northwest when there is growing involvement in arts and social justice, there has been renewed interest in the nueva canción (“new song”) movement from Latin America. Abel Rocha, Diego Coy and Patricia Mazuela, three highly skilled performers of this tradition, make up Seattle-area trio Sin Fronteras (“without borders”). They describe the music as having “vibrant rhythms, soulful melodies, and breathtaking harmonies — songs of life, humanity and love.” The song lyrics alone are some of the most beautiful poetry in the Spanish language.

The roots of nueva canción are based in the rural folk music of Chile, and spread from there to Argentina, Spain and other Latin countries. In support of the “common people,” the music makes extensive use of traditional musical forms and instruments, such as the quena, zampoña, charango and cajón, and features the guitar (from Chilean cueca). Sin Fronteras continues this tradition, adding the cuatro, Argentinian bombo (bass drum), and Venezuelan harp.

The three musicians of Sin Fronteras all immigrated to the U.S.

Rocha is a Mexican-born vocalist interpreter of “Jarocho music” and player of many instruments native to Mexico, Venezuela and Argentina. His sound is influenced by Andean, mestizo and criollo rhythms: a blend of indigenous, African and European influences. He has recorded three CDs in collaboration with the group Correo Aereo, and he is also a member of Los Flacos.

Born in Santiago de Cali, Colombia, Coy came to the U.S. in 2003. He plays the quena, quenacho and the zampona in addition to other woodwinds and percussion instruments that are native to countries in the Andean region. He applies jazz improvisation to traditional music in a unique way. Coy also performs with Los Flacos and the Micho & Diego Duo.

Mazuela is originally from Chile and has been living in the U.S. for the past 32 years. A cofounder of Sin Fronteras, she also cofounded Pasajeros, a playback theater group. Mazuela’s passion for the nueva canción movement keeps her busy organizing artistic events that promote social justice and awareness through all aspects of the arts: theater, visual arts, dance, music and spoken word.

There is a suggested admission donation of $5 for the concert, which will be collected at the door. There are no advance ticket sales. This concert is funded in part by the National Endowment for the Arts, 4Culture, and Northwest Heritage Resources. For more information, call 360-642-3446 or email info@northwestheritageresources.org
