You think music is all about the sound? Nope. In Seattle, interpreters perform at concerts to translate for deaf fans. “The craft is harder than it sounds: At its best, it’s being prepared and knowledgeable enough to communicate the essence of an artist’s lyrics over the actual words. By law, venues must provide interpreters upon request. And while local ticket sellers report just a handful of requests a year — typically for big-name events — it’s been particularly busy for KeyArena, which has trotted out U2, McCartney and the Stones.”
