Come hear some people with skillz strum their guitars — it’s the annual Ibero-American Guitar Festival and this year it is being held at the National Museum of the American Indian. The fest will pay homage to the sounds and traditions of Ibero-American regions and cultures and will especially highlight the contribution of the guitar to these cultures. The event is organized by the Association of Ibero-American Cultural Attachés in conjunction with The Smithsonian, and will honor the legacy of one of the greatest Latin-American composers, Heitor Villa-Lobos. While full access to the concerts will cost you, ($50 for the weekend or $30 for each day or $20 for each concert) concerts at noon on Saturday and 1 p.m. on Sunday are free. Check out the full schedule, which also includes lectures and a screening of a bio of Villa-Lobos.
