Of late, it has become a trend in Kollywood for various music directors to collaborate for a song. In Mariyan, music director AR Rahman recorded a song with Yuvan Shankar Raja.
In Ennamo Edho, Imman asked Anirudh to sing a song. Now for Shankar's magnum opus Ai, music director AR Rahman has asked Anirudh to sing a song and the recording was done on July 1.
Later, Anirudh tweeted that he had great fun singing the song and thanked AR Rahman and Shankar. Shankar tweeted back:"Anirudh sings! Arr rocks! Ai tunes coming soon!"
