 Following the release of Porque Te Quiero , Gutiérrez and De la Fuente suggested the studio musicians to stay permanently in the group , a proposal which they accepted . The new band members used to be part of another Chilean group called Los <unk> , whose music was influenced by the psychedelic funk , which they incorporated in their next recordings with Los Ángeles Negros . Later , in October 1969 , they recorded and released their second album , Y Volveré . The record contained songs which helped the band become popular throughout Chile and Latin America , including " Y Volveré " ( cover version of " <unk> @-@ moi " by Alain <unk> with new lyrics by De la Fuente ) , " Como Quisiera <unk> " , and " Murió la Flor " .
