Nobody knows prolific and mercurial Atlanta rapper Young Thug quite like audio engineer Alex Tumay. The Queens, NY, native has been the only professional able to keep up with the talented rapper, harnessing his abilities on the Slime Season trilogy of mixtapes, I’m Up and JEFFERY. An unheralded yet essential presence on a number of pivotal Atlanta hip-hop albums, Tumay has also worked with 21 Savage & Metro Boomin’s “Ocean Drive,” Travis Scott on Rodeo and lent his ear to the track “Highlights” from Kanye West’s The Life of Pablo.

In his Studio Science at the 2016 Red Bull Music Academy, Tumay discusses how he finished up Young Thug’s JEFFERY in an Uber, “Ocean Drive,” and much more.
