I knew this piece by Berta Rojas interpretation, and It's a bit different, isn't it? Altought I took a look at John Williams' interpretation and it seems pretty much like this one. Why is that? I mean, Berta is from Paraguay, as well as Agustin Barrios. Did she have some information we didn't?
By the way, this is listed as Valse, is this really right? I'm not an expert, but this sound like a south american rythm often reffered as "galopada", anyone?
Congratulations, anyway, beautiful interpretation!
