Los Tekis ("boys" in Quechua) is a folklore group from the Jujuy province of Argentina. It is formed by (vocals, quena and charango), Juanjo Pestoni (drums), (wind and backing vocals), Pipo Valdez (winds and charango), Walter Sader (guitars) and Pucho Ponce (bass). Even though they have been together for a long time, their appearance on the Festival de la Serenata de Cafayate (1991) is generally considered their debut as a group. Their repertoire consists of music styles from the northeast of Argentina and Bolivia, such the carnavalito and taquiraris, which they play on various traditional instruments.
