Technically, the band putting out the EP is called "Los Unidades" - but here's Coldplay's manager talking about it:
“It was a real honour to help further the Global Citizen movement by putting together this release alongside Chris and Parlophone. We’ve ended up with so many incredible performers, and we’re all extremely proud of the finished EP. May it be the first of many.”
The EP features Pharrell, Stormzy, Wizkid, Tiwa Savage, Dave Guetta, Cassper Nyovest, and Stargate
