Within the Colombian tropical sound revolution, which occurred in the 60s and 70s, Afrosound was one of the most daring and interesting projects. Its foundation, at the dawn of the 70s, places it almost at the end of the experimental sonorous process that would be formalized under the name of Chucu-Chucu, at a time when most of the groups had standardized their creative proposals. Afrosound appeared like a fresh breeze in the musical circuit of the country, experimenting with sounds from soul, Latin jazz, rock and funk, without losing the rhythmic pulses of urban cumbia from which musicians had drawn influence during the previous decade. Afrosound, more than a musical group, was a laboratory of sonorous experimentation that we could well consider the pioneer of a type of tropical Colombian rock.
