Problem: Background: The Doors were an American rock band formed in 1965 in Los Angeles, with vocalist Jim Morrison, keyboardist Ray Manzarek, guitarist Robby Krieger, and John Densmore on drums. The band got its name, at Morrison's suggestion from the title of Aldous Huxley's book The Doors of Perception, which itself was a reference to a quote made by William Blake, "If the doors of perception were cleansed, everything would appear to man as it is, infinite." They were unique and among the most controversial and influential rock acts of the 1960s, mostly because of Morrison's lyrics and charismatic but unpredictable stage persona. After Morrison's death in 1971, the remaining members continued as a trio until disbanding in 1973.
Context: Despite Morrison's conviction and the fallout from their appearance in New Orleans, The Doors set out to reclaim their status as a premier act with L.A. Woman in 1971. The album included rhythm guitarist Marc Benno on several tracks and prominently featured bassist Jerry Scheff, best known for his work in Elvis Presley's TCB Band. Despite a comparatively low Billboard chart peak at #9, L.A. Woman contained two Top 20 hits and went on to be their second best-selling studio album, surpassed in sales only by their debut. The album explored their R&B roots, although during rehearsals they had a falling-out with Paul Rothchild, who was dissatisfied with the band's effort. Denouncing "Love Her Madly" as "cocktail lounge music", he quit and handed the production to Bruce Botnick and the Doors.  The title track and two singles ("Love Her Madly" and "Riders on the Storm") remain mainstays of rock radio programming, with the last of these being inducted into the Grammy Hall of Fame for its special significance to recorded music. In the song "L.A. Woman", Jim Morrison scrambles the letters of his own name to chant "Mr. Mojo Risin". During the sessions, a short clip of the band performing "Crawling King Snake" was filmed. As far as is known, this is the last clip of the Doors performing with Morrison.  On March 13, 1971, following the recording of L.A. Woman, Morrison took a leave of absence from the Doors and moved to Paris with Pamela Courson. He had visited the city the previous summer and was interested in moving there to become a writer in exile.
Question: who are the doors
Answer: 

Problem: Background: 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.
Context: On July 11, 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 Barao Vermelho, for the soundtrack of the 24th season of Malhacao, a Rede Globo series. With Lee's inclusion, the band recovered some old songs for its live setlists, including Titanomaquia's "Sera Que E 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 will 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 will 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 next 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. On December 2017, they announced that they had already started recording the album and that it would be released via Universal Music. In January 31, they announced that the opera rock would be released in early 2018 and that its title would be 12 Flores Amarelas.
