The unit of 'Rock On 2' shot major portions of the film in Shillong towards the end of 2015 and given that it's a musical, the cast would often sit down together to jam.

Sangma is a music aficionado and over a decade ago, had released a Garo music album in which he debuted as a singer trilling about love and peace.
