Purchase a card that is specifically designed for the occasion --- whether you are celebrating an anniversary, a graduation or a birthday. Place the ticket or tickets inside the card. Write a message inside the card informing your friend that you thought he might enjoy this special event because you know he loves this band or musician, and place the card in an envelope.
Purchase a CD of the singer or band and place the concert tickets inside the CD case. Wrap the gift. As he unwraps your present, ask him to look at the CD or tell him you want to glance at the insert. Once he opens it, he will immediately see the concert tickets.
Make a gift basket of band-related items, such as a tee shirt, a poster or individual photographs of the band members. Wrap each item individually and place and tape the concert tickets along the bottom of the basket. When he takes out each item, he will find the concert tickets at the bottom.
