The Gang 90 As Absurdettes was one of the first groups of Brazilian rock in the early '80s. They were not highly successful, but had a hit and remained part of the history of the genre. Júlio Barroso, a Brazilian rock journalist who was an enthusiast for soul music, reggae, and new wave, wrote for several music magazines since the '70s, trying to promote the arousal of the rock made by Brazilians. After a period in New York, he returned to Brazil and made a performance in São Paulo's alternative venue Paulicéia Desvairada, with his sister Denise (Lonita Renaux), Alice Gwendolyn (Alice Pink Punk), Maria Elisa Capparelli Pinheiro (May East), Herman Torres, Luíza Maria, Wanderley Taffo, Guilherme Arantes, Lee Marcucci, Gigante Brasil, Otávio Fialho, Luiz Paulo Simas, Beto Firmino, Gilvan Gomes, Paulo Le Petit, and Curt, forming the group the Gang 90 As Absurdettes. The experience was successful and the group also performed at the Lira Paulistana, the Morro da Urca (Rio), and in September 1981, at the MPB-81 national festival with the new wave "Perdidos Na Selva." The song was released as a single by the label Hot in the same year, but with the scarce popularity for the incipient Brazilian rock, Barroso returned to the U.S.

In 1983, with the confirmed commercial potential of the new genre and several recording companies hunting for new people capable of being popular, Júlio Barroso returned to Brazil and signed with RCA. Adding his wife Taciana Barros to the previous formation, they recorded the LP Essa Tal de Gang 90 As Absurdettes, released in 1983. "Nosso Louco Amor," also released as a single, sold almost 100,000 copies after its inclusion in TV Globo's soap opera Louco Amor. Unfortunately, problems with drugs and booze led Barroso to fall from his apartment's window at the 11th floor. His sister Denise died a little after of AIDS. From 1985 to 1987, Taciana tried to keep the Gang 90 (without the As Absurdettes and with a completely different formation) going, releasing two albums (Rosas Tigres, 1985) and Pedra 90, 1987), but the group finally abandoned its activities. ~ Alvaro Neder, Rovi
