India, March 13 -- Sound of Silence is the name of this sculpture, made using 4,000 brass bells, which now stands tall at the recently inaugurated expanded section of T1, Indira Gandhi International (IGI) Airport. Soon the commotion of travellers will fill this space, but even then, this artwork will be a testimony to India's cultural heritage as the bells depict "auspicious significance of peace and contemplation"....
