I caught PJ Harvey's "The Hope Six Demolition Project" tour at the Greek Theater here in Los Angeles. Allow me to tell you about that, and about psychic space, outdoor music shows, croaking for dollars, staying relevant in the face of increasing waves of nostalgia, First Aid Kit and Fiona Apple, retiring from live shows, people putting on a groovy act, jalapeno nachos and spinach wraps, the Ringling Bros. and Barnum & Bailey Circus, cannibalism, Cirque du Soleil, voicemails and chirping of many kinds.
