At the beco several important artists like Elis Regina debuted; the place also held shows by consecrated composers/performers like Johnny Alf, Leny Andrade, Dolores Durán and Silvinha Telles, among others. Young amateur Mamo used to sit in with those artists, and also to take tips from Edison Machado, another regular. With his group the Youngsters, which was one of the most important supporting groups of Jovem Guarda, Mamo opened in 1968 the leading popular music room in Rio, the Caneco. Already an experienced session man, he recorded with other studio professionals (the Philips keyboardist and arranger José Roberto Bertrami and the bassist Alex Malheiros) the Marcos Valle soundtrack for the film O Fabuloso Fittipaldi. As Valle, an Odeon artist, was impeded of receiving credit for it, the trio signed the album as Apolo IV. With one of the tracks, Azymuth, becoming a hit, the trio took it as its definitive denomination, launching in 1975 their first album, Azymuth. \r Mamo participated in several jazz festivals like the Playboy Jazz Festival, Berkeley Jazz Festival, Monterrey Jazz Festival, Montreux Festival, Circus Theater Holland, Quartier Latin Berlin and the Brazilian Fest Athens/Greece.
