Titas (Portuguese pronunciation: [tSi'tas]) are a rock band from Sao Paulo, Brazil. Though they basically play pop/alternative rock, their music has touched a number of other styles throughout their 30-year career, such as new wave, punk rock, grunge, MPB and electronic music. They are one of the most successful rock bands in Brazil, having sold more than 6,3 million albums as of 2005 and having been covered by several well-known Brazilian artists and a couple of international singers. They were awarded a Latin Grammy in 2009 and have won the Imprensa Trophy for Best Band a record four times.

In November 1985, Tony Bellotto and Arnaldo Antunes were arrested for heroin traffic and transportation. It This considered by the band as the climax of their first crisis, started with the first two albums low sales. Also, the episode made so much of an impact in the band, the next album, Cabeca Dinossauro, released in June 1986, contained a lot of tracks criticizing the public institutions ("Estado Violencia" and "Policia"), as well as other "pillars" of the Brazilian society and indeed society in general ("Igreja" and "Familia"). The heavy and punk-influenced rhythms and the forceful lyrics, characteristic of the band in this phase, are fully represented in this album which is considered by the critics one of the best works of the group and one of the landmarks of the Brazilian rock.  Jesus Nao Tem Dentes No Pais Dos Banguelas, released at the end of 1987, continued in the same vein as the previous album in tracks like "Nome aos Bois", "Lugar Nenhum" and "Desordem", however adding samplers in tracks like "Coracoes e Mentes", "Todo Mundo quer Amor", "Comida" and "Diversao". After some international performances, the band recorded some of their hits in live Montreux Festival and released Go Back in 1988. The biggest hit to come out of Go Back was a live version of the song "Marvin" which is a re-invented version of "Patches" by Clarence Carter made famous by Elvis.  The producer Liminha (a former adjunct member of Os Mutantes) was always an important associate of the band since Cabeca Dinossauro, and this association arrived to its climax in O Blesq Blom, one of the most popular productions of the band by that time. Some of the prominence tracks: "Miseria", "Flores", "O Pulso" and "32 Dentes". One of the prominent features of this work was the special guest appearance of a couple of improvisors, called Mauro and Quiteria, discovered by the band in a beach in Recife.
