Founded in 2015 by Rachel Maria Cox, the collective started as a tour and festival which saw Cox, alongside "freak-folkie" Ess-Em, perform with local acts in Melbourne, Adelaide, Sydney, Canberra, Newcastle, Wollongong and Brisbane, building up to the first ever Sad Grrrls Fest run over two days in Sydney. The project received a huge amount of positive feedback, but the question everyone was asking was "what's next for the Sad Grrrls?"

Never one to take a break, RMC immediately started work on Sad Grrrls Club Records, a DIY record label that would help bring together not only non-male musicians, but also recording engineers, producers, mastering engineers, photographers, graphic designers, videographers and artists to create an ongoing project that could help promote gender diversity in the industry.
