On 12 February 2010, Titãs announced in their official website that drummer Charles Gavin would leave the band for personal reasons. Gavin later stated that he was physically and mentally exhausted because of the tours and album releases. The quartet continued their performances of the Sacos Plásticos tour with drummer Mario Fabre, who has remained with the band since then as a session member. Fabre was suggested by Gavin himself. When asked about the status of Fabre in the band, Bellotto explained that "he is the official drummer! He's the drummer of Titãs! But he isn't one of Titãs, because our history began long ago, at Greek mythology... " During an interview, keyboardist Sérgio Britto said the band was planning to start recording a new album in 2011. Nothing else was said since then, until March 2013, when they revealed they were starting to work on a new album, to be released in the second half of 2013. The album would be self-produced, and, according to Britto, it would be "a mixture between Cabeça Dinossauro and Õ Blésq Blom". In January 2012, the band announced a live performance in company of ex-members Arnaldo Antunes, Nando Reis and Charles Gavin. The show would celebrate the 30-year career of the band, and would include guest performances of other friends of the band, and there were plans for a DVD release. According to Miklos: The reunion took place on 6 October 2012, in São Paulo. For the first time since 1997's Acústico MTV, the seven original members of the band reunited for a one-night performance. According to Bellotto: The band gathered in Reis' house to discuss the reunion - it was the first time since Fromer's death that all seven members met. In 2013, Titãs performed new songs live, part of their Titãs Inédito (Titãs Unseen) tour. They were planning to begin work on a new album in April or May 2014. Miklos said the album was likely to be "heavy, dirty and mean". Later, Britto confirmed that the album would be released in early May and that the band was already recording songs for it, but it was yet to be titled. In March, radio Globo FM announced that the album would be actually released in April and would feature 14 tracks. On 16 April, the band announced that the album was ready and would be really released in May, via Som
