Originally conceived by Stefan Pruett and John O'Keefe as an informal project with the aim of experimenting with electronic music, Peachcake developed into a national touring band.

In the latter part of 2006, Peachcake joined forces with Jim Adkins' label, Western Tread Recordings, to release a split EP along with local Arizona band Less Pain Forever.

in early 2008, the band parted ways with Sidecho Records and later released the album with the help of Warner Music Group/ADA and Los Angeles based production company, Subtractive, through their own imprint label called The Planet Awesome!

The group toured in the beginning of 2009 to support the album playing shows with MC Lars, Danger Radio, The Scene Aesthetic, Young The Giant, Get Back Loretta and Dear and the Headlights, as well as appearances at Daytrotter, Canadian Music Week and Bamboozle Left.

[5] Since the release of This Wasn't Our Plan, Peachcake has performed with and supported many national acts both locally in Arizona and on tour in the past few months, including shows with Cage The Elephant, Future Islands, Peter Murphy, She Wants Revenge, Washed Out, Neon Trees, Meat Puppets, T. Mills, Japanther, and Electric Guest.

[6] In July 2012, Peachcake performed at the ten-year anniversary of Slottsfjell in Tønsberg, Norway, featuring New Order, Janelle Monáe, Friendly Fires, Wolfmother, Chase & Status, Noah & The Whale and more.

Mike McHale, Peachcake band member and longtime friend of Pruett, coordinated a memorial charity concert honoring Stefan on January 15, 2022, at Crescent Ballroom in Phoenix, AZ.
