This is a Quena made by the workshop of Adrian Villanueva, a master craftsman of the traditional Andean instrument, the Quena. Adrian Villanueva was a world-renowned performer who was active as a Quena player for the highly popular Andean music groups "Rumillajta" and "Kallawaya." He also performed in Japan as part of Kallawaya, making him a familiar figure to Japanese folklore music fans. Afterward, he established his own workshop to produce Quenas and Charangos, creating high-quality instruments with designs informed by his experience as a performer. His Quenas, in particular, are renowned for their stable intonation and rich resonance. His workshop was also known for producing Mauro Núñez-style Villaseca-type wooden peg Charangos. However, Adrian Villanueva tragically passed away in 2020 due to COVID-19. Instruments from his workshop are no longer being produced and have become rare. This instrument is recommended for those who love Andean music or wish to add a rare piece to their collection. No further details are available beyond what is shown in the photos.
