Villa Lobos, Heitor - Etudes - Polishing No. 1. Stopping there.

Etude No. 1
Incredible version by 12 year old Grace Sheppard.

Decent version by Seyoung Park. Look at that guitar position! Almost like a cello!
Nice one by Sunshine Guitar. Note that she uses two harmonics for the two ending bars. Yeah!

Lesson by Dennis Azabagic. VERY useful.

Rare Bream:
1, 2
3, 4
5, 6, 7

Number 2 and 11 are interesting too, but probably not interesting enough.
