Take a piece paper and fold it into thirds. Put a picture on the cover along with a strong benefit headline. Use the fold-in panel for testimonials from satisfied customers. Use the three inside sections to profile your music and sound products and services. Place your contact information on the back panel.
Bands can include media interviews, reviews, and so forth.
Others can include testimonials from happy clients, letters of recommendation, and media coverage, etc. You have about 30 seconds to make the sale, often less. You must grab your listener right away and hold attention. That's when the prospect is going to make the decision. A good band shot is a must.
