Liying Zhu plays Una limosna por el amor de Dios by Paraguayan composer Agustìn Barrios Mangorè (1885-1944) on a 2013 Antonius Müller. Her relaxed and accurate touch is fantastic. You can learn more about her via her D’Addario bio page: “Born in Kunming city of Yunnan province in China. Liying started to learn classical guitar when she was a child and immediately fell in love with this charming instrument. She began to study with Professor Chen Zhi, the leading guitar professor in China at her age of 11.” This comes via Siccas Guitars and their greatYouTube channel!
