You haven't heard of Brasil 66? They are quite good and the Tamba Trio has music that is similar to Brasil 66. As fro Astrud Gilberto, see if "The Girl from Ipanema" rings a bell (Astrud has a voice that can turn me into pliable putty).
Still does not ring a bell. I like classic rock, like from the 60s and 70s, some early 80s. Now I maninly listen to Christian Rock. Will have to search for them on Limewire and listen.
