Rogério Tolomei Teixeira, known professionally as Rogério Skylab, is a Brazilian singer-songwriter, lyricist, classical guitarist, poet, essayist, record producer, actor and former television presenter. Describing himself as a "corpse within MPB", his unique musical style which granted him a passionate cult following is characterized by minimalism, repetition and eclecticism, and his lyrics and poems are permeated by grotesque, shocking and offensive imagery; acerbic allusions to popular culture; metafictional devices; absurdist scenarios; pessimism; profanity; nihilism; and scatological and black comedy – although he denies that his work is purposefully humorous.

Skylab II is a live album by the Brazilian musician Rogério Skylab, the second in his series of ten eponymous, numbered albums. His first ever live album, it was self-released in 2000 and recorded during a gig at the Hipódromo Up in Rio de Janeiro in the same year. Löis Lancaster, vocalist of now-defunct experimental rock band Zumbi do Mato, was a guest musician on the album, providing additional vocals for the track "Samba". Nine years later, Lancaster would return for Skylab IX. The album is considered one of Skylab's finest by fans and critics alike, and the songs "Convento das Carmelitas" and "Carrocinha de Cachorro-Quente" eventually became set list regulars after appearing here in recorded form for the first time. A studio re-recording of "Cu e Boca" would appear six years later on Skylab VI; afterwards, "Ato Falho" and "Música Suave" were re-recorded for Caos e Cosmos, Vol. 2 in 2022.
