Flávio Basso, better known by his stage name Júpiter Maçã and by its English-language variation Jupiter Apple, was a Brazilian singer, songwriter, multi-instrumentalist and filmmaker. Before beginning a solo career in 1994, he was already known for being a founding member of bands TNT and Os Cascavelletes, both pioneers of the Rio Grande do Sul rock scene in the mid-to-late 1980s/early 1990s.

Os Cascavelletes were a Brazilian rock group from Porto Alegre, Rio Grande do Sul. One of the first rock bands from Rio Grande do Sul to acquire mainstream success nationwide alongside its "sister project" TNT, they were characterized by their irreverent style inspired by 1950s-era rockabilly culture and acts such as The Rolling Stones and The Beatles, and by their comical, profanity- and sex-laden lyrics. Some of their most famous compositions are "Sob um Céu de Blues", "Menstruada", "Estou Amando uma Mulher", "Eu Quis Comer Você" and the 1989 hit "Nêga Bombom".
