Problem: Background: Interpol is an American rock band from New York City. Formed in 1997, the band's original line-up consisted of Paul Banks (vocals, rhythm guitar), Daniel Kessler (lead guitar, vocals), Carlos Dengler (bass guitar, keyboards) and Greg Drudy (drums, percussion). Drudy left the band in 2000 and was replaced by Sam Fogarino. In 2010, shortly after recording finished for the band's fourth album, Dengler left to pursue personal projects.
Context: On March 6, 2009, the band announced on its website that it was working on songs for a fourth album. The album was recorded in Electric Lady Studios during spring 2009. In an interview, Fogarino referred to the album as having gone back to the original sound of Turn On the Bright Lights. It was later claimed by Banks that it would not sound anything like their debut album and that there is some very "classical stuff going on" with it. No news about the album surfaced until late April when the band sent an email directing users to a free download of "Lights", the first officially released song. Citing management changes at the label, the band left Capitol records prior to the album's release, signing again with Matador Records.  The band's fourth album (self-titled) was officially released on September 7, 2010. It was Dengler's last effort with Interpol. In an announcement on the band's website on May 9, 2010, it was revealed that he had left the band sometime after the album's completion. When the remaining members toured in support, he was replaced by multiple players, including David Pajo (formerly of Slint and many other bands) on bass, and Brandon Curtis of The Secret Machines on keyboards and vocals. The album was released on Matador Records in the US, and on Cooperative Music for Europe, Australia and Japan. On February 2011, Pajo announced that he was no longer touring with Interpol, in order to dedicate more time to his family. Pajo was subsequently replaced by Brad Truax.  The band was announced as the opener for the third and fourth legs of U2's 360deg Tour, and subsequently the band announced eighteen US shows to take place over the third leg of U2's 360deg Tour, but only three of them went ahead after Bono's back injury cancelled U2's entire third leg. The band toured the UK and Ireland in November and December 2010.  On June 22, 2010, a promotional video for "Lights", directed by Charlie White and featuring Lola Blanc, was made available for free download on the band's official website.  The band opened for U2 on their rescheduled tour date at Soldier Field in Chicago, Illinois, on July 5, 2011, and remained on U2's 360deg Tour for the remainder of the summer.
Question: Why did Carlos Denger depart from Interpol?
Answer: he had left the band sometime after the album's completion.

Background: Talking Heads were an American rock band formed in 1975 in New York City and active until 1991. The band comprised David Byrne (lead vocals, guitar), Chris Frantz (drums), Tina Weymouth (bass), and Jerry Harrison (keyboards, guitar). Described by critic Stephen Thomas Erlewine as "one of the most critically acclaimed bands of the '80s", the group helped to pioneer new wave music by integrating elements of punk, art rock, funk, and world music with avant-garde sensibilities and an anxious, clean-cut image. Former art school students, who became involved in the 1970s New York punk scene, Talking Heads released their debut
Context: David Byrne, Chris Frantz, and Tina Weymouth were alumni of the Rhode Island School of Design in Providence, Rhode Island. There, Byrne and Frantz formed a band called "The Artistics" in 1973. Weymouth was Frantz's girlfriend and often provided transportation for the band. The Artistics dissolved the following year, and the three moved to New York, eventually sharing a communal loft. Unable to find a bass player in New York City, Frantz encouraged Weymouth to learn to play bass by listening to Suzi Quatro albums. They played their first gig as "Talking Heads" opening for the Ramones at CBGB on June 5, 1975.  In a later interview, Weymouth recalled how the group chose the name Talking Heads: "A friend had found the name in the TV Guide, which explained the term used by TV studios to describe a head-and-shoulder shot of a person talking as 'all content, no action'. It fit." Later that year, the trio recorded a series of demos for CBS, but the band was not signed to the label. They quickly drew a following and were signed to Sire Records in November 1976. The group released their first single in February that year, "Love - Building on Fire". In March 1977, they added Jerry Harrison (keyboards, guitar, backing vocals), formerly of Jonathan Richman's band The Modern Lovers.  Their first album was released soon afterwards, Talking Heads: 77, which did not contain the earlier single. The album received considerable acclaim and spawned what became the group's first charted single, "Psycho Killer". The song was released to the radio just months after the serial killer known as the Son of Sam had been terrorizing New York City, prompting many to assume some eerie connection. However, it was later revealed that Byrne had written the song nearly four years earlier.
