Trencito de los Andes

**Trencito de los Andes** is an Italian musical group and cultural association that was founded in 1974 by brothers Raffaele Maria Clemente and Felice Maria Clemente in Rome. The group is dedicated to the study and performance of Andean music. In 1987, alongside Laura Grasso, they established the "Trenino delle Ande" cultural association. Known for their deep exploration of Andean musical traditions, Trencito de los Andes embarked on significant research journeys through Peru, Bolivia, and Ecuador from 1986 to 1987. Their discography includes notable works like "Yawar Fiesta" (1983), "¡Hermano Residente!" (1992), and the well-received "Zig Zag" (1993), which celebrated the music of Otavalo, Ecuador. The group was also involved in prestigious collaborations with renowned composer Ennio Morricone. In 2006, they concluded their activities as Trencito de los Andes and refounded as "Il Laboratorio delle Uova Quadre" following the release of "Opus Primum."

Some of their works are represented in your list, such as "¡Hermano Residente!" and "Zig Zag" parts, though "Zig Zag" was released as a single entity in 1993. It's unclear if the other titles listed are part of their official discography from the information available.
