Concert Party Theme – The Venue
Make a red carpet leading up to your front door using red wrapping paper, or a roll of red plastic table cloth.
Make your own Hollywood Boulevard walk of fame. Draw stars on your driveway or walkway with chalk, and write the names of your guests in them.
Make a sign for your front door that says “Stage Door, band and roadies only”.
Make a stage area. Paint gigantic speakers on a plain white sheet. Hang it from the ceiling. Hang strings of clear Christmas lights around the edges of the sheet.
Use star shaped balloons on the food table, and have some floating through the party room.
Hang posters and pictures of popular bands around the room.
Turn your bathroom into a dressing room. Have a supply of glitter hair spray, hair gel, stick on body jewels and temporary tattoos. For slighter older kids, supply make up and body glitter as well.
Give each concert goer a glow stick they can wave in the air while others sing and dance.
Concert Party Theme – The concession stand
Serve foods you would normally find at a concert. Chicken fingers, hot dogs, pizza, soft pretzels, French fries served in paper cups, nachos and individual bags of popcorn.
Put sparkling juice or cider into plastic champagne flutes, and serve them on a silver tray. If you don't have a tray, you can make one out of cardboard covered with aluminum foil.
Serve a star shaped cake that says “You rock”, “You're a superstar”, or “Rock ‘n Roll forever”.
