Most people dance while getting drunk to avoid a hangover. What better way of promoting whisky at a nightclub than mixing it with a bit of music? Ballantine’s Finest whisky has come up with a new marketing marvel, which has spirits in a new bottle with an external coating that tends to react to music. This bottle, which is dark blue in hue, is the brain-child of a London-based packaging agency, ‘The Core’ as a part of Ballantine’s ‘Listen to Your Beat’ campaign. The label on the bottle is made with an electroluminescent material that appears like an equalizer responding to music.
