I just came across the Canadian guitarist, Drew Henderson, playing the Allegro from Johann Sebastian Bach’s 2nd Violin Sonata, BWV1003. His performance is brilliant on many levels and the fact that he is playing an 8-string guitar allows him to add in bass notes that would otherwise be impossible on a standard 6-string guitar.
And, here is another magical and virtuosic performance of Joaquín Rodrigo’s Zapateado from Tres piezas Españolas. It seems that Drew does fine on a six-string, too. : )
Hope that inspires you all!
