These 10- to 14-year-olds from Vienna study academics and music while at a boarding school for six months, and tour the world performing their music for the rest of the year. Tonight, 23 members of the Vienna Boys Choir, one of the oldest and most prominent choirs across the globe, will take the stage at a SoBo venue to showcase their talent.

Their debut tour to the country is titled A Passage to India, and the excited bunch not only bring a fresh sound to the city, but also give us a dose of history, for it survived World War I sans any state or church affiliation. "Background or nationality does not matter as long as one wishes to learn," says Gerald Wirth, president and artistic director of the choir, who is travelling with the boys. But some of the boys leave after they turn 15. "Because their voice starts cracking at that age. But they are welcome to stay," he explains.
