This work is also called Choros 7 (Septuor) = (Septet). I'm assuming the tam-tam is left out of the count (like when Ringo plays the tambourine in a Beatles song. Though they're still the Fab Four, I guess. So never mind.)
Choros #07 is dedicated to Dr. Arnaldo Guinle, who generously gave Villa the money for his first trip to Paris.

This is one of the first scores to be published in the Villa-Lobos Digital project of the Academia Brasileira da Música.
The ASV disc of the first seven Choros, with soloists from the Orquestra Filarmonica De Gran Canaria, includes an excellent version of Choros #07.
...as does the new BIS recording with the musicians of the Sao Paulo Symphony Orchestra.

The premiere of the work was on September 17, 1925, at the Salao do Instituto Nacional de Musica in Rio de Janeiro.
I don't imagine it's that easy to round up this group of instrumentalists, but it's nice to see so many records in the Villa-Lobos Concert database (more than 25 as of March 2011).
