I worked for the Studio Orchestra at BYU-Hawaii. For their first ever performance, the director wanted to create an engaging experience for the audience. We came up with the idea of creating "Capitol Cards." The orchestra was playing music from the jazz golden age of Capitol Records. We made cards that would go into every program. Some were common, others were rare. Featured on these cards were arrangers, albums, or performers. Audience members were encouraged to ask around to find all of the cards. It was a huge hit!
