Old Lime Tree, by Russian composer Sergey Rudnev. Played here by Yuri Liberzon.
Beautiful solo playing.
Xavier arranged this, played all the instruments, and recorded and edited it himself. Bravo!
It’s called Mangoré, por Amor al Arte (Mangoré, for the Love of Art). It’s about the legendary Paraguayan guitarist and composer Agustín Barrios, also known as Agustín Barrios Mangoré. The movie should be out August, 2015.
