In American culture, when we think of classic soul, chances are the names that pop into our heads are among the likes of Otis Redding, Wilson Pickett, Marvin Gaye, and many others from Motown, Stax, and various labels around the country. In Brazil, the two names you are most likely to hear when talking about soul music are the recently popularized in America, Jorge Ben (thanks to the likes of Dusty Groove and the Tropicalia resurgence) and the virtually unrecognized Tim Maia.
If any were to be compared to the westernized soul sound, it would be Tim Maia. Although don't get me wrong, his recordings were undeniably Brazilian. Unlike Jorge Ben though, Maia was able to mix these westernized elements into his brand of crooning soul that later developed into some of the funkiest sounds in the Western Hemisphere (much like Marvin Gaye's development, in fact).
It's important to look at Brazilian music not only as a melting pot of Bossa Nova, Samba, and its many traditional elements, but also as a nation that was able to take elements from African traditional music and put their own spin on it. Maia is one of the masters of Brazilian soul music, and if I spend my entire life dragging his presence to America, then so be it. It's a worthy cause.
