Indian Classical Music and its lore has the power to move people. As an expression of this passion, Taj Mahal Tea and Ogilvy India came together to create a one-of-a-kind musical installation, the Megh Santoor. With every rain shower, the rainwater interacts with the santoor strings recreated on the billboard, which then performs a rendition of the Raag Megh Malhar. Inspired by the rains and, in fact, activated by them, the installation was bestowed with a Guinness World Record for being the "Largest Environmentally Interactive Billboard."
