Lala - Assar - Sattar were the first music director trio to work in Hindi films. The group consisted of Lala Gangavane and Sattar Khan, musicians who played Indian percussions like dholak and tabla, and Assar Mohammed Khan, who had worked as an assistant to the likes of Nisar Bazmi and A.R. Qureshi. The trio split after composing the music for just two films - "Jahan Sati Wahan Bhagwan" (1965) and "Sangram" (1965). Lala Gangavane and Sattar Khan regrouped later and composed music for several films under the screen name Lala - Sattar.
