Kids Commuters, take cover! It’s Pop Goes the Classical Week 2.0 on Kids Commute from Interlochen Public Radio. All week we’ll be hearing pop songs played on classical instruments. Back in the day, it was called a theme and variation; one composer takes another composer’s theme and makes changes to put their own twist on it. Nowadays, we call that a cover song. Regardless of what label you put on it, the Kids Commute theme thought you’d like to hear a new batch of pop music performed with a classical spin by today’s classical performers.
