FOR THE BBC RADIO 1'S SUMMER MIXES, WE CREATED THE OPEN WINDOW SONGS. A RALLYING CRY TO SWING OPEN YOUR WINDOWS AND FILL THE BRITISH SUMMER WITH MUSIC. A TVC LAUNCHED THIS MONTH LONG ON AIR ACTIVATION. DURING THE 2 HOUR MIX DURING THE SUMMER WE ASKED THE DJ'S TO MOTIVATE THE BRITISH TO ROLL DOWN THEIR WINDOWS AND TURN UP THE TUNES.
