Moses and his school friends are deaf, but like most children, they have a lot to say. They communicate in American Sigh Language, using visual signs and facial expressions. This is called signing. And even though they can't hear, they can enjoy many activities through their other senses. Today, Moses and his classmates are going to a concert. Their teacher, Mr. Samuels, has two surprises in store for them, to make this particular concert a special event.
