After several years of studying music in his native Colombia, Roberto López' musical journey brought him to Canada. He obtained a B.F.A. with a specialization in jazz studies at Concordia University and completed additional (jazz and classical) composition, arranging and orchestration courses with professors Christopher Smith, Andrew Homzy and Isabelle Panneton. Roberto perfected his guitar technique by studying with musicians such as Bill Coon, Roddy Ellias and Ernesto Ocampo (Carlos Vives, Bloque). He has also studied Colombia's folk music, string and wind native instruments, afro-Colombian percussion, as well as South American music from Cuba, Brazil, Puerto Rico and Dominican Republic.

He has recorded, played in and composed for several groups, including Brazilian bands Matita Peré (contemporary samba/baiao), Quilombo (Brazilian popular music) with whom he performed at the Festival International de Jazz de Montreal'98, Armenian star Harout Zenian (PE-KO) and Colombian pop group Doble U.C. . He recorded and arranged for Heather McLeod's CD Graffiti Love Song (Bellamuse Productions) and toured through out Canada with her. He was the founder and musical director for Grupo Azúka (salsa/Latin jazz), which performed extensively in the Montreal area, and his new band: Roberto López Project, which explores Colombian and Cuban rhythms in an urban environment.

Roberto has also composed for award winning films, including productions such as "Open Secret" (National Film Board of Canada), "L'argent" (ISCA), "Chronique urbaine" (Peripheria), and "A Saddle Tree" (Artefacto Films/Peripheria). His song “Oye Latino” was featured in the movie of the week Hollywood Wives, starring Farrah Fawcett (CBS).
