For director Damien Chazelle and composer Justin Hurwitz, not much has changed since they attended Harvard together — at least not when it comes to how they work together.

"So much of it is just like it was when we were 20, in terms of me being at the piano, making little demos, emailing them back and forth," Hurwitz tells EW ahead of the release of the duo's latest collaboration, Babylon.

Never mind the fact that they've both since won Oscars — Best Director for Chazelle and Best Original Score and Best Original Song for Hurwitz, both for 2016's La La Land — and seen their careers skyrocket since their work on 2014's Whiplash.
