The announcement has somewhat slipped under the radar due to the fact that the flyer has the artist's birth names on it and not their stage names.
The LA-based collective have confirmed that 100% of proceeds from the concert will go to the ACLU, whose mission is to defend and preserve the individual rights and liberties of US citizens.
The organisation has been thrust into the limelight once again after President Donald Trump signed an executive order halting all refugee admissions and temporarily barring people from seven Muslim-majority countries.
"The ACLU is quite literally defending our freedoms," RL Grime told LA Weekly. "I think we have a responsibility to defend our choices, our beliefs, our right to speak and our right to perform. I am only able to do what I do because I felt safe and protected and supported in my pursuits. I want everyone to feel that safety."
The show will take place at LA's The Fonda, with RL Grime, Baauer, Shlohmo, Groundislava and the whole of the WeDidIt crew.
