A couple of years ago, when Shruti Pathak sang a ghazal by famous Pakistani classical singer Farida Khanum at Hard Rock Café, she didn't expect to move the crowd to tears. "The venue is the go-to place for people who dig rock and metal, but I was singing a ghazal, something you wouldn't expect there," she says. The high point of the night was when the audience started singing along. "It was surreal," recalls the artiste who got the big break in 2009 when she sang Mar Jawan from the movie Fashion, and then went to sing famous soundtracks from films like Ra.One, Criminal and Anjana Anjaani. The HRC experience drove home a lesson: While there's a young audience for the genre, the challenge lay in making it palatable.
