Since the launch of their music video “Thrill” in late 2014 (840k+ views and counting), Band-Maid has been turning heads with their heavy sound and the inevitable reaction, “Are these cute girls really playing?”

Yes, they’re playing—and playing for keeps at that, adding a series of demo and rehearsal videos to their YouTube channel to put all doubts to rest. No air guitar here: just girls who're ready to put a smile on your face (even their video description for “Real Existence” teases, “Welcome, master…”) with a serving of solid rock.
