Timothy Steis Plays the Allegro from 2nd Violin Sonata BWV 1003 by Johann Sebastian Bach (1685-1750). This comes via his YouTube channel. Video by Drew Henderson. Point of interest, Timothy is also a luthier and he’s playing his own guitar. You can see his guitars at his website. While working on his undergrad he started building guitars and has continued studying both music and apprenticing as a luthier during his masters degree. Where does he find the time?!
