For his new album, Residente had neurologists study Bad Bunny’s brain

Puerto Rican artist Residente is currently gearing up for the release of his sophomore album. He's already offered the project's lead single, "Bellacoso," a collaboration with Bad Bunny. In a new interview, he opens up on the process behind the LP, in both the scientific and creative sense: "[The album is] going to be about everything that I have inside of my head... because of that I kept brainstorming and I said, ‘Oh I have to study my brain, and then I have to study other people’s brains, and then I have to study animals’ brains.'"

That pursuit reportedly led him to the neurology departments of Yale and New York University, where Residente teamed with professors to study brain wave patterns on worms, monkeys, mice, and even Bad Bunny. Using electroencephalogram (EEG) tests, he tracked communicative rhythms that he eventually translated into beats for the project: “I wanted to prove to the people that even though we are different in certain ways, we can connect with each other with our brain frequencies." Results from his and Bad Bunny's EEG tests can be heard on "Bellacoso."

Residente's as-yet untitled forthcoming album is due out later this year.
