Aros Guitar Duo play an arrangement of Prelude by Belgium/French composer César Franck (1822-1890) on two 2016 Duo Yulong Guo Chamber Concert Doubletop guitars. This comes via the amzing Siccas Guitars and their great YouTube channel. Quite a pretty arrangement with some nice phrasing and shaping by Mikkel Egelund Nielsen and Simon Wildau. I’m ashamed to say I don’t really know my Franck but this is from Prelude, Fugue and Variation in B minor, Op.18 which you can hear and follow the score on piano via this YouTube Video.
