OK Go is an American rock band originally from Chicago, Illinois, now based in Los Angeles, California.
 The band is composed of Damian Kulash (lead vocals, guitar), Tim Nordwind (bass guitar and vocals), Dan Konopka (drums and percussion) and Andy Ross (guitar, keyboards and vocals), who joined them in 2005, replacing Andy Duncan.
 The band is known for its often quirky and elaborate one-take music videos.
Andy Scott Duncan (born 20 May 1975) is an American musician, best known for being a founding member of the Chicago band OK Go, playing lead guitar and keyboards.
 He appears on their first two albums, the eponymous "OK Go" and its follow-up album "Oh No".
 Since leaving the group, he has worked on numerous films and commercials as a sound designer and composer with directors Eric Lynne of Partizan Films, Grzegorz Jonkajtys of Industrial Light and Magic, Bastiaan Koch of Marauder Films, to name a few.
The musical rock band OK Go has earned considerable fame for their creative but often low-budget music videos, most of which have been promoted through Internet video sharing sites like YouTube.
 Many of these have become viral videos; the 2006 video for "Here It Goes Again", in which the band performed a complex routine with the aid of motorized treadmills, has received over 50 million views four years later.
 Their video for Needing/Getting, released February 5, 2012 in partnership with Chevrolet, debuted during Super Bowl XLVI and has over 32 million views on YouTube.
 Samuel Bayer, who produced many music videos in the 1990s, asserted that OK Go's promotion of music videos on the Internet was akin to Nirvana's ushering in the grunge movement.
 Many of the videos also use long or single-shot takes, which "Salon"' s Matt Zoller Seitz says "restore[s] a sense of wonder to the musical number by letting the performers' humanity shine through and allowing them to do their thing with a minimum of filmmaking interference".
 The success of OK Go's music first won the band the 14th Annual Webby Special Achievement Award for Film and Video Artist of the Year.
 The video for "This Too Shall Pass" was named both "Video of the Year" and "Best Rock Video" at the 3rd annual UK Music Video Awards.
"This Too Shall Pass" won the LA Film Fest's Audience Award for Best Music Video, UK MVA Awards – Music Video of the Year Winner 2010, among others.
"The Writing's on the Wall" is a song by American rock band OK Go.
 It was released on June 17, 2014, as part of the band's EP "Upside Out", and is also the first single from the band's fourth studio album "Hungry Ghosts".
 On the same day, the band released a music video in which the members use props to create optical illusions, reflecting the song's description of a relationship that fails because the couple has different points of view.
 Like previous OK Go videos, it is structured as a one-shot music video.
 The many YouTube views of the video caused the song to debut in the top ten of the US "Billboard" Hot Rock Songs chart, as well as number one on the Bubbling Under Hot 100 Singles chart.
Paracadute is a record company owned by OK Go.
 OK Go left their previous record company, EMI, because of a disagreement between the band and the label.
 OK Go reissued their album, Of the Blue Colour of the Sky, with Paracadute taking care of the promotion and distribution of the album reissues.
 OK Go's lead singer, Damian Kulash, announced the new label in a video posted to the band's YouTube channel.
