Conjunto Orquestal Puno - Peruvian sounds from the 1950s

I picked up this strange Peruvian album in a charity shop in Brighton a couple of weeks ago. I can't find anything on the internet about the orchestra, but some of the songs on the album are Huaynos which are :

the result of the meeting of traditional mountain music with its high-pitched vocals, insistent beat, and breathy flutes - and more commercial, urban sounds, including those of Colonial music from Spain. Like contemporary North American musical hybrids, moreover, the kinds and combinations of instruments are often surprising: harps and harmonicas, mandolins and saxophones, panpipes and accordions, as well as guitars, violins and charangas.

To my ears, this is some strange stuff with its weird blend of Andean and western instruments and its melancholy sound.
