Shahrdad Rohani in Yanni Live at the Acropolis concert

Shahrdad Rohani(Persian: شهرداد روحانی) is an Iranian composer, violinist/pianist, and conductor. His style is contemporary (sometimes even New Age), especially when compared with his mentors/inspirations, Anoushiravan Rohani and Javad Maroufi. He is probably most known for arranging and conducting the Yanni Live at the Acropolis concert, an open-air concert with the London Royal Philharmonic Concert Orchestra in the Parthenon, Athens, Greece. This concert was acclaimed by both critics and audience and became the most widely viewed program ever shown on Public Television in United States and is the second best-selling music video of all time.
