Recomendations of Reinassance pieces for guitar duet
 

Greetings I was looking for recomendations of Reinassance pieces for classical guitar duet.

It's for an exam, I'm not from the states or England so we don't have the same system, but legally it should have the difficulty of a grade 8-9 piece in the US/UK system. Or in other words it should have a difficulty similar to Piazzolla's Tango Suite (the 1st/2nd movement) or Brouwer's triptico for guitar duet; as they are both suites and pieces we have to present in the same exam.

Thanks.

Frederick Noad has some very good ones in his Guitar Anthology series "The Renaissance Guitar".
Good ones are: "Toy For Two Lutes", "Drewrie's Accordes", "The Flatt Pavin" and its companion piece "The Galliard to the Flatt Pavin".
There are others throughout the book. Noad does a good job in this series.
I have no idea where these fall in the grading scale scheme of things that you mentioned.
However, I can say that these pieces can be quite challenging when played up to tempo and with good phrasing, but more importantly, they are fun to play and very pleasing pieces to the listener, when done right.
(Isn't that what really matters? :))

In addition to the good recommendations above from Noad's Renaissance book,
from the same book I also like the Francesco da Milano piece to which Joanne Matelart added a second part, in combination called 'Recercate Concertante'.
Might be worth checking out.
