Tahuantinsuyo was formed by folk musician Guillermo Guerrero from Ayabaca of the Peruvian Andes in September 1973. The group dedicates its performances of the traditional music from the Andean countries that once formed the "Inca Empire" (known as Tahuantinsuyo in Quechua, the native language). This area comprises of six countries: Ecuador, Perú, Bolivia, Chile, Argentina and Columbia.

Members of TAHUANTINSUYO are: Guillermo Guerrero (Founder and Director), Fernando Leyva, John Freire, Andrés Jimenez, Alcides Loza and Saúl Guerrero, and Cesar Vele. Members are family and friends who share the goal of keeping the traditional Andean music alive and helping their people to identify with their culture.

They began their musical journey in NYC’s "El Café Latino Americano" and "The Alternative Museum" where they became popularized in the U.S.

They performed in various U.S. venues including: Carnegie Hall, Avery Fisher Hall, Constitution Hall In Washington D.C., The Museum of Natural History, The Field Museum of Chicago, The Brooklyn Museum, to name a few.

In addition to recordings at major record stores ("Tahuantinsuyo Music of the Andes" and "Music of the Andes and Argentina"), they made two recordings for the Museum of Natural History. They were invited to the 150Th Anniversary celebration of The Smithsonian Institution in Washington D.C. and to the international music festival "Voice of Asia" in Alma Atta, former Soviet Union.

Early 1993, they won a CAPA award by QPTV for their music video from the Andes and another award in July 1999 called “Alliance for Community Media’s Hometown 2000.”
