Thursday was audition day for performers in the New York Subway. About sixty musician applicants from the Tri-state area were called back to perform on a balcony at Grand Central Terminal in front of a panel of judges. Each year, some 20 new acts are added to 25 designated underground performance spaces.
The Metropolitan Transportation Authority's Music Under New York (MUNY) program has strived "to reflect the culture and diversity of the people of New York City" by seeking musicians from many cultures. Underground, you could hear Chinese percussion instruments, a Flamenco guitar, steel drums, a Senegalese kora, or see dancers to music by Michael Jackson's Thriller.
Auditioning through the MTA ensures that a musician will not be kicked out of stations by the police. The MTA also makes sure that the musicians are actually good - everyone knows that there are quite a few subway musicians who are plain out awful.
Today, more than 100 approved soloists and groups play in the city's subway with a total of 150 weekly performances.
