Maria Fumaça

Oberdan Magalhães and Luiz Carlos are credited, and we take the latter to be the drummer Luiz Carlos Batera, which the Wikipedia pages do not say outright. It is the first track of Maria Fumaça and runs 2:22; the title means steam train. It was the opening and closing theme of Rede Globo's telenovela Locomotivas in 1977, and the Locomotivas soundtrack on Som Livre carried seven band tracks. Rolling Stone Brasil notes it was an instrumental that charted, a difficult feat, and describes the brass attacks as widely known, a blend of samba, forró, funk, jazz and disco. It was issued in 1977 as a Atlantic single backed with "Mr. Funky Samba", and again as a Mr Bongo seven-inch in 2016.

The band played it at the 1978 Caetano Veloso concerts, at the Teatro Carlos Gomes, billed Maria Fumaça - Bicho Baile Show, and critics praised the instrumentalists, especially Oberdan. Setlist.fm has only 14 sparse setlists. Mos Def and Incognito have recorded the group's songs, but sources do not say which. It is instrumental, so there is no lyric to interpret, and we cannot say whether our upload is the studio original.
