Ricardo Diaz Romero was an amateur guitarist who studied with Antonio Sinópoli in 1909. At the request of Domingo Prat, he contracted Miguel Llobet for his first tour of Argentina, which would soon extend to other countries of America and would be repeated several times. Romero dedicated his arrangements of the Colombian bambucos Entre las peñas and Casta paloma, to Miguel Llobet.
