A four-way conference call between us, Sharon Isbin, and Ayaan and Amaan Ali Bangash makes one thing crystal clear. The two sarod-playing brothers have unfettered respect for the Grammy-winning American guitarist, since they consider it an "honour" to be collaborating with her for an unusual concert slated for later this week. It's a word they use multiple times during the phone call. And Isbin, on her part, tells us from Kolkata that she's as enthused about the performance as anyone else.

The gig is unusual because it isn't everyday in our country that the worlds of Indian and western classical music collide on stage. Isbin is one of the world's leading lights in the latter genre. But her introduction to western classical music was wholly by accident. "We were living in Italy for a year when I was nine years old, and my older brother asked for guitar lessons. But he didn't want to study classical. He wanted to be Elvis Presley. So, I volunteered to take his place and raised my hand out of family duty," she reveals, adding that while her father was a nuclear scientist, it was her mother who ensured that she received a solid musical education.
