| that's a whole world to explore but here's a few with the classic tunes --
Antonio Carlos Jobim -- Unknown (or Inedito, same disc released under different titles). This is the late-80s "New Band" w/ Jacques and Paula Morelenbaum, Daniel and Simone Caymmi, and Jobim's wife and kids. Generally pretty straightforward pop arrangements of a bunch of great tunes ("pop" isn't meant here in any derogatory sense. It's not a jazz record, that's all that's meant)
For the original '50s-60s arrangements (Claus Ogerman etc) there's a pretty good compilation called "Antonio Carlos Jobim -- Composer", combines a couple of classic LPs and a few other tracks.
For jazz interpretations, pretty much every Eliane Elias disc has a bossa or two -- a couple are all Jobim, Plays Jobim is a great one. Fantasia has a really great version of Chega De Saudade w/Eddie Gomez.
Also check out Joe Henderson's "Double Rainbow", half the record is with a Brazilian rhythm section, the other half american jazz.
that's probably enough to get you started, those wil lead you to more stuff. ah one more, there's an Elis Regina 2-disc set "Samba Jazz & Bossa", bunch of great stuff on that one too, some Brazilian funk, etc.
ok one more -- Joao Gilberto, Chega De Saudade. Pretty much where it all begins. |
