Stupid Rock were formed in 2015 by Hank Dynamo of Pinball, D.J.M. and Jane Moore, with Durf Al Gumby later joining in 2016. Although the group disbanded in 2018, due to Hank Dynamo departing to create The Dynamos, the group still gets back together every few years or so to record a new EP or album, such as A Very Stupid Christmas! in 2021 and Butt, fArT, PP, Boobs in 2022.
