Emch doesn't speak of Perry as some dated figurehead, confined to documentaries and historical anecdotes. Instead, he appears as a Yodalike figure, constantly giving obscured wisdom that may seem like the ramblings of a ganja-addled mind, but his cryptic words are laced with glimmers of genius. Once, before a show, Perry instructed the bass player to "play a major scale up and down, like a monster walking in space." Anyone familiar with the space-age boom of dub bass can recognize how apt the imagery is. "When he communicates his musical ideas he does it in metaphors, which I think can be so much more inspiring to people," Emch says. "You understand the feeling, and you create something from that feeling."
