Must admit that I rather liked the original thread, and, as some other posters have pointed out, it was a very useful way of learning about (or being directed to) new and unheard music.
To the point then; just now, I am listening to some Azymuth, an amazing Brazilian band from the sixties, (a few years ago, I saw them play live, in a jazz club, an incredible experience) who combined lounge jazz, south American rhythms, and oozed cool. When I saw them, the three musicians were well into their sixties and still complete masters of their music. Try "Jazz Carnival" and "Last Summer in Rio"; "Pieces of Ipanema" is possibly their best known song.
Cheers and good luck
