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.
Question: Why did he leave?
Answer: to focus on his personal projects.

Background: Color Me Badd is an American contemporary R&B group that was formed in Oklahoma City, Oklahoma. The original members of the group were lead singer Bryan Abrams (born November 16, 1969), second tenor Mark Calderon (born September 27, 1970), second tenor Sam Watters (born July 23, 1970) and baritone Kevin Thornton (born June 17, 1969). They formed in 1985 and broke up in 1998 before reuniting in 2010, with various lineups since. As of 2016, they operate as a trio with Abrams, Calderon and Adam Emil.
Context: Thornton and Abrams became friends in junior high school, and Watters and Calderon became friends in grade school. The four met in the mid-1980s while attending Northwest Classen High School in Oklahoma City. They were all members of the school choir. The group originally formed in 1985 as Take One, but changed their name to Color Me Badd to avoid confusion with an a cappella band named Take 6. Watters selected the name, after a horse at the racetrack named Color Me Bad. They aimed to be a vocal group in the vein of New Edition and New Kids on the Block. They first performed together in a school talent show, influenced by doo-wop a cappella groups of the past, such as Sam Cooke, The Temptations and the Four Tops. The group came up with a plan to spontaneously audition for any big name acts playing in Oklahoma City. They met Robert Bell of Kool & the Gang on May 27, 1987, when they were in Oklahoma City for a performance. They auditioned for him and he introduced them to his then-road manager, Adil Bayyan, who would become Color Me Badd's manager and convince them to move to New York City to pursue a record deal. They also sang for Huey Lewis and the News, Sheila E. and Ronnie Milsap, and opened for Tony! Toni! Tone! in Oklahoma City in 1988. One afternoon in 1989, Thornton saw Jon Bon Jovi in a movie theater and called the other band members to join him. They waited for him to leave the theater and then sung the 1961 doo-wop hit "Daddy's Home" a cappella for him. Bon Jovi invited them to be his band's opening act the following night, to perform in front of 20,000 audience members. They moved to New York City on September 23, 1989. In 1990, they bumped into Tony! Toni! Tone!, who got them into the ASCAP Music Awards. There, Color Me Badd approached producers Jimmy Jam and Terry Lewis and started singing for them. The producers advised that, being a multicultural group, they write a half-English, half-Spanish song. They wrote "I Adore Mi Amor" back in Oklahoma City with their producer and friend Hamza Lee. Giant Records executive Cassandra Mills heard a tape of the band singing the song, and they signed with Giant on August 11, 1990.
