The document proposes a summer music festival campaign called "Heatwave" for teenagers in Vietnam. The campaign will include a two-day music camp and live concert near the beach to promote new music, encourage music appreciation, and reinforce Coke as the perfect companion for summer fun. Key elements are engaging teens through online music platforms and contests to select participants for the camp, installing pop-up visuals and lounges around cities, and building an iconic structure inspired by the Sydney Opera House to host the main events. The goal is to lift teens' spirits through refreshing music experiences and remind them that Coke supports Vietnamese youth and music.
