The group was formed sometime in 2010 when a producer known only as RΠЯ started seeking out someone with whom to perform newly written songs. Through a mutual friend, Sarah P. was introduced to RΠЯ, and they soon began to perform together. The band name was conceived as a pun on Kypseli, a neighbourhood of Athens. The band has completed four North American and three European headline tours, performing in 63 cities across 18 countries so far. They have also played at numerous festivals around the world, including Coachella Festival, Parklife, The Great Escape, and Fun Fun Fun.
On 17 January 2014, Sarah P. announced she was no longer in Keep Shelly in Athens. In March 2014 the band announced a new singer, Myrtha. In 2017, the band released a new LP, Philokalia, armed with another new singer, Jessica Bell.
In 2021 the main member of Keep Shelly in Athens announces a new collaborative singles series with guest vocalists from around the world. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
