[1] 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".

According to founding members Flávio Basso and Nei Van Soria, the band's name is a portmanteau of the words "cascavel" ("rattlesnake" in Portuguese) and "Marvelettes", in a reference to the eponymous American girl group popular in the mid-1960s.

They formed Os Cascavelletes the same year after being joined by Frank Jorge and Alexandre Barea (a future founding member of heavy metal group Rosa Tattooada).

[5] The track "Estou Amando uma Mulher" became a major hit after airplay in radio stations of the time and its inclusion in SBK Records' compilation Rio Grande do Rock.

[7] Jorge was replaced by Luciano Albo and Humberto Petinelli joined them as keyboardist for their debut full-length album, Rock'a'ula, released by Odeon Records in 1989.
