Probably a lot less than you do, but more than your average American who watches ESPN and American Idol.
Off the top of my head, I have the usual 60s stuff by Edu Lobo, Milton, Maria, Marcos Valle, Menescal, Tamba Trio and Four, Milton Banana, Elis Regina, Quarteto Em Cy, Nara Leao, Mendes, Gilbertos, Jobim, Carlos Lyra, Vinicius, Baden Powel, Jorge Ben. Not their complete discographies of course but certain albums. Also have a few artists whose names escape me who had stuff issued in the US on Atco or Audio Fidelity.
My Bro in law has that Jorge Ben Dusty reissue that was mentioned, and that's a gem.
Love the Blue Brazil collections of stuff from the Odeon label.
Don't worry too much about what I have or don't have. I'd just like to know if anyone's been bowled over by any recent reissues or comps of any 60s Brasilian stuff along the lines of what I mentioned.
