Tamba Trio - Tamba (RCA Victor Brazil, 1974)
with Luiz Eça (p, kybd, vo); Bebeto Castilho (b, fl, sax, vo); Hélcio Milito (d, perc, vo)
I only discovered this recently, and it's knocking me out! It's comparable to the Tamba 4's We and the Sea, which is much more well-known in the US (since it was released domestically on A&M in '67). This 1974 release actually reverts to the original early-60s trio lineup, with Milito returning to the drum chair.
Along with José Roberto Bertrami (Azymuth), Egberto Gismonti, and Jovino Santos Neto (originally with Hermeto Pascoal's 80s group), Luiz Eça is one of the most interesting Brazilian pianists/keyboardists I've heard.
