Stage presence is a real thing. The best bands, the best musicians, have this aura that is hard to describe in tangible words, but let’s just say you know it when you see it. Björk, Lady Gaga, Beyoncé, they have that thing that rivets you when they perform. A lot of it has to do with what they are wearing on stage, that mixture of fantasy and make-believe, of mystery and impracticality, the kind of oh-so-important fashionable art that pumps up the music.
