Audio equipment firm Harman's JBL division, has a new ad campaign for the Indian market with music star A.R. Rahman as the ambassador. The ad shows a valley in Ladakh with a nomadic musician carrying his drums across the barren terrain which transitions to bamboo being cut to make flutes in a lush green forest in Thailand, a guitar being strung in a workshop bathed in the warm glow of flickering lamps and finally, one arrives at a pristine white living room where the guitarist is sitting, strumming.
