Barbara Klaus-Cosca (accordion) and Tina Klement (guitar) have dedicated themselves to performing Latin American world music. In their concerts, the instrumental duo combines classical music, tango nuevo and jazz, captivating their audience with expressive melodies and rhythmic lightness. The musical crossover repertoire ranges from the Brazilian bossa nova of Chelso Macha-do to the Argentinean tango nuevo of Astor Piazzolla to the Mexican sandunga or the Venezuelan waltz.
