Junoon means "obsession" in the Urdu language.  It is the name of one of Pakistan's and perhaps South Asia's most popular rock bands. The group is based in Karachi, and was formed in 1990 by guitarist, songwriter and medical doctor Salman Ahmad. Sometimes when Junoon performs in the United States, an American-based singer of Indian origin, known as Falu joins the group.  VOA's Ravi Khanna brings us a glimpse of Falu's life and music.
