Los Pleneros de la 21 perform "Carmelina," a traditional plena in tribute to the great plenero Marcial Reyes Arvelo, a founding member of the group and author of the piece. Jose Rivera, in his singing, places himself firmly in the classic school of the plena, referencing pleneros who influenced his musical upbringing. By including this version with panderetas (different sized circular frame drums), and a güiro (gourd rasp) Los Pleneros de la 21 give the listener the opportunity to taste the fresh, simple, and wonderful flavors or the traditional creole plena.
