Yuvan is no more part of the project, for reasons unspecified. Five young composers, including Hip Hop Aadhi and a student of A R Rahman, will score music for the movie, sources say.
They also say Aadhi has already composed a song, which impressed Sundar a lot. An official announcement on other composers will be made soon.
Vishal plays the lead role in Aambala, which has Hansika as the heroine. Ramya Krishnan, Aishwarya and Kiran play key roles.
