Earlier, it was speculated that Bairavaa's audio is being planned to release on 25th of December, but now, it is said that the audio might be out by the first week of December, which is just two weeks away from now.
It is known that the songs of Vijay's films always release a month before the theatrical release of the film. So, going by that, this looks like a trustable information, but when we last spoke to the director of the film, Bharathan, he told us that nothing has been finalized yet.
So, we would have to wait for an official announcement from the team to know about the audio release date of this Santhosh Narayanan musical.
