X Suns started as Keith Furtado, Trent McIntyre, and Adam Tricoli in Seattle sometime in 2009. They started playing live at the start of 2010 (as Ten Suns). 

In Oct. of 2011, They recorded a 5 song EP with Justin Armstrong at Electrokitty Studios. Soon after, they changed their name to X Suns ("X" as the roman numeral for ten), after finding out about a Canadian band of the same name. After self-releasing the E.P. on CD and Digital Download in January of 2012, the band decided to add Skippy King (Formerly of the Seattle band Patrol) as their second guitarist. They continued as a four-piece until May of 2012, when Keith Furtado decided to part ways with the band. He was replaced by Richard Burkett (from the Seattle sludge-metal band Giza) in August of 2012.

Now with a heavier sound, they began to craft new songs and re-work old ones. In March of 2013, they entered the studio to record what would become "The Greys" EP.

The Greys was self-released digitally, and on a limited run of cassette tapes on October 31st, 2013. 

Prior to the release, Richard Burkett quit the band to focus on his band Giza. He was quickly replaced by Erick Hohnstein-Von Etten, formerly of the band Claymore (from Port Orchard, WA).
