Aussie producer Chris Emerson (aka What So Not) has linked up with Oliver Tree and none other than Killer Mike for a new song called "Mr. Regular."

The defiant new cut arrives as the latest preview of What So Not's upcoming sophomore album Anomaly, which has been teased for some time and is now confirmed for release on Sept. 16 via Counter/Sweat It Out.

“It’s one of the biggest songs I’ve ever been part of, tied up in red tape for too long. I know how much the fans and community want this one," says What So Not, adding: “I showed Mike the demo after working on a bootleg/remix for his project Run The Jewels. 'Mr. Regular' is about the difficulty that we face through our childhood and career progression as clueless superior figures try to control and shape our path."
