Since 1977, visitors to Times Square have discovered the rich harmonic sound texture by artist Max Neuhaus that emerges from a large underground subway vault at 46th and Broadway. As part of Performa '09, two contemporary musicians, Tony Conrad and Jennifer Walshe, held a 20 minute concert by playing newly reconstructed 1913 Futurist instruments with the Neuhaus’ sounds above the subway grates.

“Times Square” by Max Neuhaus has produced its deep, long tones from 1977 to 1992 and then reinstated by the DIA Arts Foundation in 2002 with support from the Times Square Alliance and MTA Arts in Transit. Visitors may experience the sound work 24 hours a day, seven days a week.
