Q.I. 69

Q.I. 69 formed in the early 1990s in Rio de Janeiro's Vila Kennedy neighborhood, with vocalist Rogério Skylab as their frontman. Their debut album came out in 1994, and they put out several more records through the late '90s, including 'Power' in 1996 and 'Quatro Estações' in 1998.

Their song 'É Só Acreditar' and others like 'Hoje Não É Meu Dia' and 'Uma Vida Bem Melhor' show the band's mix of rock, reggae, and Brazilian styles. They had a raw sound that drew listeners, but their explicit lyrics and unconventional approach kept them from fitting neatly into the mainstream.

Over time, the lineup shifted around Skylab, with musicians like Robão on guitar, Gordo on bass, and DJ Nuts on turntables at the core, plus others like Fernando Catatau and Mauro joining later. Their music often dealt with urban life and personal struggle, which connected with some audiences while drawing criticism from others.
