Who Are You?

It was silent, all too silent for their liking.
The band sat together in the back of the bus, Joey was zoning out, the rest of the percussionists were talking quietly, the two guitarists were asleep, the vocalist was pacing around and looking at the ground while Sid and Paul were eating dry cereal together.
They heard a bang - startled, they all jumped... only to realize it was something they never expected.
