About You

Our band is large. And while there’s plenty of room for all kinds of personalities and skill sets to succeed, there are certain qualities that will help you thrive here.

Like a never-accept-less work ethic. An exceptionally low ego-to-talent ratio (none of the first, tons of the latter). A relentless craving to push past your limits and try new things. The smarts and the humble confidence to take on big challenges, make mistakes fast and early, embrace tough feedback, then recover quickly with fresh, startlingly perfect solutions. A fearless willingness to defend great work. And a tendency to totally geek out on music.
