Hey thank you Bucky! Yeah you're right, challenging. I've learned guitar by myself watching youtube video, and the first complete percussive fingerstyle tune I learned was exactly the one you're talking about: Drifitng by Andy Mckee. I made a post about it here.
Yes, it's wonderful, I watch almost everyday new marvelously talented guitarist emerging from nowhere on Candyrat records. (Youtube channel)
I will, thanks a lot!
Cheers, Troilo
