Based in Chula Vista and National City, Volcano Egg features Matthew Reilly (Nevergreens) and Terrance Greer who met in 2007 while in the seventh grade. Throughout high school (2009 - 2013), they each encouraged each other's respective musical projects, but never collaborated.
Teaming up in late 2015, they began to improvise, with Reilly recording every attempt (whether the attempt was successful or not). These songs, recorded over a period of two days, eventually became their first demos, Ghost Leslie.
Their EP In the Court of Law was released in 2016.
