 After recording the songs in Santiago , the band returned to San Carlos and became a quintet when drummer Federico Blasser joined them . In the meantime , their single received high airplay in some Chilean provinces , and because of De la Fuente 's voice , attracted the attention of Jorge Oñate , the director of Chile 's Odeon Records , who asked the band to go to Santiago to record an LP for his record company . However , only De la Fuente and guitarist Mario Gutiérrez eventually went . Oñate quickly contacted three studio musicians — drummer Luis Ortiz , keyboardist Jorge González , and bassist Miguel Ángel " Nano " Concha — with which De la Fuente and Gutiérrez recorded Los Ángeles Negros ' debut LP , Porque Te Quiero , released in 1969 .
