Livre records. On 28 April, they announced the title, cover and release date for the album, which is called Nheengatu and was released on 12 May. In August 2015, they released Nheengatu ao Vivo, a live album and DVD with songs from their Nheengatu Tour. In February 2016, they opened a Rolling Stones Brazilian show for a second and third time, this time at the Morumbi Stadium in São Paulo, on two different dates. 2016-2018: Miklos' departure and rock opera On 11 July 2016, vocalist, guitarist and founding member Paulo Miklos announced he would leave the band to focus on his personal projects. He was then replaced by session member Beto Lee, son of Brazilian notorious rock singer Rita Lee. His first recording with the band is a version of "Pro Dia Nascer Feliz", originally by Barão Vermelho, for the soundtrack of the 24th season of Malhação, a Rede Globo series. With Lee's inclusion, the band recovered some old songs for its live setlists, including Titanomaquia's "Será Que É Disso Que Eu Necessito?" and "Nem Sempre se Pode Ser Deus". They also started to have Bellotto sing in some songs. Also in 2016, the band announced a new album for a possible 2017 release. According to Bellotto, it would be a rock opera, and the band intended to enter the studio until mid-2017 so the album could be released in the year's second half. Drawing inspiration from albums such as The Who's Quadrophenia and Green Day's American Idiot, the over 30-track rock opera would have its story written by Hugo Possolo and Marcelo Rubens Paiva. By April 2017, Mello said a handful of tracks were ready. Also in April, the band started a tour called "Uma Noite no Teatro" (A Night at the Theater) with a show that was also the inaugurating event of Shopping Villa-Lobos' theater Opus. The tour included three new songs: "Me Estuprem" (Rape Me), about sexual harassment and rape; "12 Flores Amarelas" (12 Yellow Flowers); and "A Festa" (The Party). By that time, none of them were expected to be featured in the band's new album. On 23 September, however, the band performed them again during their show at the Rock in Rio 7, and this time they were announced as part of the new project. In December 2017, they announced that they had already started recording the album and that it would be released via
