On Thursday, August 6, at 7:30 pm, Brazilian instrumental group Choro das 3 will perform a family-friendly concert at the West Tisbury library. Choro das 3 is made up of three sisters and their father, who first started to play as a band in 2003. The music they play is called choro, a form of urban jazz native to Brazil that shares a similar feel with New Orleans jazz, ragtime, and bluegrass. Choro das 3’s mission is to revive the choro tradition in Brazil, where they join several other young people rediscovering this music, and to spread choro around the world. The concert is free and open to the public.
