Merrill Garbus, the creative force behind musical act Tune-Yards, has never been one to shy away from speaking up about topics she cares about. (Though we’re still awfully partial to that time she made fun of Justin Bieber, Diplo, and Skrillex.) But now, fans have a chance to hear the artist speak about some of the issues and ideas closest to her heart in a new 90-minute video from her appearance at the Red Bull Music Academy in Montreal last month, streaming exclusively at The A.V. Club. (You can find out more about the RBMA here.) It’s billed as a “lecture,” but really, it’s a revealing sit-down interview in which a series of prompts finds Garbus holding court on everything from vocal techniques from around the world, to the personal nature of political struggles and even the concept of equality, in ways both artistic and more broadly humanist.
