Sometimes the artists you think will be scary as hell one-on-one turn out to be the nicest people around. A couple of years ago, I interviewed avant-garde vocalist Diamanda Gálas, whose art is often terrifying and who regards audience and cameras with the withering glare of a witch queen. She turned out to be open and friendly and laugh-out-loud funny, and the hour or so we spent on the phone was a pure pleasure.
