I just bought some new music by the Brazilian composer, guitarist and keyboardist, Guillermo Klein at the iTunes store. He is apparently heavily influenced by Hermeto Pascoal, whom I love. I got Guillermo's album "Los Gauchos, Vol. 3" and it's blowing me away. I know that Ben Monder is featured on guitar but I have no clue who else plays on it. Is anyone familiar with Guillermo Klein and more specifically, knows who is playing bass on that particular album? Thanks!
