This is an excellent site created and managed by some teenager from Brazil (if I remember correctly). There are probably 500-1000 albums, many of them otherwise unavailable. I believe you can download for free, but I paid ten bucks for either a month or year-long subscription to some download expediting program, and I probably have about 100 of the albums.
Otherwise, if you don't want to deal with that and don't mind paying money, check out
Stan Getz/Charlie Byrd - Jazz Samba
Stan Getz/Joao Gilberto - Getz/Gilberto
Antonio Carlos Jobim - Wave, Tide, The Composer of Desafinado Plays, Jobim (separate albums)
Bud Shank/Laurindo Almeida - Brazilliance, Vols 1-2, both of which are available from the site I reference.
Happy listening
