Here's one from another Peruvian group. Los Wembler's from Iquitos, founded in 1968 by Solomon Sanchez with his five sons. Along with Los Destellos and Juaneco y su Combo, they were one of the pioneers of the chicha style of cumbia. The 5 brothers still perform and tour to this day and are touring Europe in 2018.
This is their third album "La Danza Del Petrolero" (The Dance of Oil)...
