Beginnings and first album, ''Ratatat'' (2001–2005)
Evan Mast and Mike Stroud first met as students at Skidmore College. They started working together in 2001, recording several songs under the name "Cherry". Stroud had previously toured with Dashboard Confessional in 2000. Ratatat debuted in 2003 with the release of the single "Seventeen Years" on Mast's and his brother Eric's record labelAudio Dregs in the US and Rex Records in the UK. Mike Stroud had been a touring member of Ben Kweller's band, but he "had enough" by 2003 and, after two years of touring, left the band after appearing on their second album, On My Way. Having signed for XL Recordings, Ratatat released their self-titled debut album, Ratatat and the single "Germany to Germany". The album was written and recorded in Mast's Crown Heights, Brooklyn apartment on his laptop. It is entirely instrumental with the exception of vocal excerpts at the beginning and end of select tracks. In the following year, Ratatat supported the band Interpol on their tour. Also in 2004, Ratatat released Ratatat Remixes Vol. 1 in co-operation with Audio Dregs, a compilation of remixed tracks by other artists, thereby garnering the attention of Rolling Stone.
Second album, ''Classics'' (2006–2008)
On August 22, 2006, Ratatat released their second album entitled Classics on XL Recordings. On October 6, 2006, Ratatat became the first band to perform a public show inside the Guggenheim Museum in New York City. On October 10, 2006, a new demo album from Ratatat titled 9 Beats was leaked online. This set of tracks does not appear on any official discography listings. 9 Beats was not an official album, the tracks consist of short instrumental electronic musical pieces and demos for their next mixtape. In 2007, this release was followed by their second volume of remixed tracks, Ratatat Remixes Vol. 2. From June 2007 until October 2008, Ratatat had Martin Bonventre accompany them on their European tour and fall shows in America as the pianist/synthesizer player. Bonventre drew much attention due to his erratic dance movements on stage. The reason for him leaving the performance is unknown.
Third album, ''LP3'' (2008–2009)

"Shiller", the first to be released, featured a special b-side, the track "Mahalo" which was later also included on the fourth album, LP4. In 2008, it was rumored that they would be signed by Star Trak Entertainment as the understudies of The Neptunes. Ratatat contributed two songs to , the debut album by alternative rapper Kid Cudi released September 15, 2009, "Alive " and "Pursuit of Happiness", the latter of which also featured MGMT.

Fourth album, ''LP4'' (2010–2014)
According to Mike Stroud in an interview with Paste Magazine released on August 4, 2009, "most of was recorded during the same studio sessions that yielded LP3". Ratatat's fourth album, LP4, was released on June 8, 2010, via XL Recordings. In 2010, Ratatat supported Vampire Weekend on their UK tour at The Brighton Centre and Alexandra Palace. Meanwhile, their song Neckbrace was used in the ski film "The Way I See It" by Matchstick Productions. In 2011, their track "Mirando" was used in Prada's SS2011 ad campaign. In August 2011, Ratatat was featured in the song "Red Alert" on CSS's new album La Liberación. On September 29, 2012 past collaborator Kid Cudi confirmed that Ratatat would be featured and producing on his upcoming third studio albumIndicud, however the collaboration didn't make the final cut after Kid Cudi decided to produce the whole album by himself, with the exception of an additional production by Hit-Boyon the track "Red Eye" featuring Haim. In May 2013 they entered the Austrian Singlecharts after the Austrian network provider A1 used "Loud Pipes" for a radio-advertisement.
The band played Coachella Festival and Governor's Ball Music Festival in 2015. They debuted their new song "Cream On Chrome" just a few hours before their night-ending Coachella set on April 11, 2015.

This is their second appearance on the annual countdown run by the Australian radio station, after featuring on Kid Cudi's "Pursuit of Happiness", which polled 33rd in the 2009 countdown.
Live performances
Ratatat's live performances bear strong similarities to the performances of the psychedelic rock bands out of San Francisco in the 1960s, with energetic light shows, swirling colors projected onto a screen, and clips of movies thrown in. Evan Mast creates and edits the videos that are projected on the screen. Many of them are included on their YouTube account. Ratatat has toured with acts such as Björk, Daft Punk, Vampire Weekend, Mouse on Mars, Franz Ferdinand, CSS, the Faint, Super Furry Animals, Clinic, Panther, and the Killers.
