With specially made instruments and a range that can emulate that of a whole orchestra, the acclaimed Guitarra a Seis bring us a colorful program that includes works written specially for the ensemble. Opening with a real feast for the ears in Bach’s lively Brandenburg Concerto No. 3, we further encounter the magical moods of Ravel’s Ma mere l’Oye, a blend of Bulgarian folk and modern music from Atanas Ourkouzounov, Tobias Krebs’ jazz-infused Suite Panamericana, and Sergio Assad’s humorous Juan Sebastian’s Bar, which alludes to Bach and Beethoven but is Brazilian through and through.
