 De la Fuente , González , Concha , and Ortíz announced their reunion in February 2009 to commemorate the fortieth anniversary of Y Volveré , originally released in 1969 . Their label EMI qualified the event as " unprecedented " . Gutiérrez did not want to participate in the Ángeles Negros reunion , fearing eventual criticism . They played together for the first time since 1974 at the Teatro Caupolicán on 14 February 2010 . The group 's reunion , however , lasted until March of that year , because of " economic issues " just before a performance at Sala SCD , a concert hall in Santiago .
