After a rough day at work, I wake the commuter train home. On board is my old friend Jesse, undercover with his electroacoustic improv troupe. He hands me a self-contained human pickup, a small white electric device which emits a constant whine. Following his lead, I affix it to the wall and twist to its active position. We then start in on a ten-minute work of physical theater and vocal experimentation, at the end of which we make believe we are two passengers on a night train across Europe.
