American actor Oscar Isaac (Star Wars: The Force Awakens, A Most Violent Year, Ex Machina, Drive) grew up playing in straight-edge punk bands and served as the front man of the ska band Blinking Underdogs. After achieving a bit of success with the Blinking Underdogs – they opened a few shows for Green Day – he lost his passion for music and trained to become an actor.

After a series of impressive roles, Isaac returned to his roots on the Coen Brothers' Inside Llewyn Davis. On Inside Llewyn Davis Isaac plays the title character and recorded every song his character sings in the movie; it was the Coens' insistence that their lead actor actually be able to sing.
