Guillermo Klein and Los Guachos June 4, 2009

Argentine pianist Guillermo Klein performs with his 11-piece group, Los Guachos. (Los Guachos, or loosely, the B*stards, comes from a common epithet in Argentina that can be used disparagingly or admiringly.) These days, the members of Los Guachos rarely perform together; Klein now lives in Spain. But in June 2008, the band celebrated the release of a new album with a one-week residency in New York.
