Question: Which band was formed earlier, Deerhunter or Civil Twilight?
Context: Anchor & Braille is the recording alias for American singer and songwriter Stephen Christian, known for fronting the alternative rock band Anberlin, before its dissolution in 2014.  Originally conceived as a side project for Christian, Anchor & Braille is now his primary vehicle for releasing music.  Christian has described Anchor & Braille as a collaborative effort, having recorded with musicians such as Aaron Marsh of Copeland, Micah Tawlks, and Kevin Daily of Civil Twilight.  Since its beginning, Christian has released three studio albums under this name, Felt in 2009, The Quiet Life in 2012, and Songs for the Late Night Drive Home in 2016. Civil Twilight is a four-piece rock band from Cape Town, South Africa, consisting of the brothers Andrew and Steven McKeller, plus Richard Wouters, and Kevin Dailey.  They are signed to Wind-up Records, and have released three studio albums — their self-titled debut album, "Civil Twilight" (2010), "Holy Weather" (2012), and "Story of an Immigrant" on July 10th 2015. Holy Weather is the second album by South African alternative rock band Civil Twilight.  Written and recorded in the years following their debut album, Civil Twilight, the album was released 26 March 2012 in both the United States and other regions including the United Kingdom, Canada and South Africa.  The album has received generally positive reviews, with many comparing the outfit to early-generation U2. Nothing but Thieves are an English alternative rock band formed in 2012 in Southend-on-Sea, Essex.  They consist of lead vocalist and guitarist Conor Mason, guitarist Joe Langridge-Brown, guitarist and keyboardist Dominic Craik, bassist Philip Blake, and drummer James Price.  In 2014, they signed to RCA Records.  Their style of music has been compared to the likes of Foals, The Neighbourhood, and Civil Twilight, and they have been played on alternative, modern rock and active rock radio. Deerhunter is an American rock band from Atlanta, Georgia, formed in 2001.  The band consists of Bradford Cox (vocals, guitar, keyboards), Moses Archuleta (drums, electronics, sound treatments), Lockett Pundt (guitar, vocals, keyboards), Josh McKay (bass), Javier Morales (keyboards, synthesizers, alto saxophone) and Rhasaan Manning (percussion, electronics). The Belt of Venus, Venus's Girdle, twilight wedge, or antitwilight arch is an atmospheric phenomenon visible shortly before sunrise or after sunset, during civil twilight, when a pinkish glow extending roughly 10–20° above the horizon surrounds the observer. Civil twilight is the brightest phase of twilight, when the sun is less than 6° below the horizon. Dusk occurs at the darkest stage of twilight, or at the very end of astronomical twilight after sunset and just before night.  Pre-dusk, during early to intermediate stages of twilight, there may be enough light in the sky under clear-sky conditions to read outdoors without artificial illumination, but at the end of civil twilight, when the earth rotates to a point at which the center of the sun is at 6° below the local horizon, artificial illumination is required to read outside.  The term "dusk" usually refers to astronomical dusk, or the darkest part of twilight before night begins. The discography of Atlanta, Georgia-based ambient and psychedelic band Deerhunter includes six studio albums, two extended plays, five vinyl singles, three split albums, and four music videos.  The band has also made appearances on a number of compilation albums.  Deerhunter was formed in 2001 by vocalist Bradford Cox and drummer Moses Archuleta.  Members to later join were guitarists Colin Mee and Lockett Pundt, and bassists Justin Bosworth and Josh Fauver.  Bosworth was killed in a skateboarding accident early in the band's career, leading to his replacement by Fauver.  Mee left Deerhunter in 2007 after scheduling conflicts preventing him from performing at a number of shows. Civil Twilight is the debut studio album of Civil Twilight.  It was officially released 6 April 2010 in South Africa and on 13 April 2010 in the United States and United Kingdom.  It features many alternative rock and classical influences.  Many have drawn parallels between the band's debut and the early work of U2 along with Muse.  Steven McKellar's vocals have been compared to that of Radiohead's Thom Yorke and Jeff Buckley.  During its original independent release by the band in 2007, the album was originally titled "Human".
