What song are they playing? I know it's Pachelbels Canon but was it arranged by someone else for guitar or are they just somehow playing the exact same version that they arranged themselves seemingly verbatim?

Good playing I guess...I'm not really into Neoclassical instrumentals tho. Especially when theyre based on pre-existing music. I'm more interested in composing your own music. Thats when your genius really shines through. I hope they can compose music as well as they can play because thats not always the case with some shredders.
