"It's special because of the way it's mounted. It's more or less 25 years of my music... and I feel very happy. We have a great orchestra from New York, and our own band... I think it's going to be special," Rahman said here on Tuesday night at a much-delayed press conference here.

Without revealing much about what fans in New York can expect from his performance, Rahman said: "We have a kind of flow where we start with the first song I did and then it's a musical exploration into what I am doing now."

"Friends and music lovers in the UK, looking forward to being amongst you and performing with my entire team," Rahman posted on his Facebook page late Thursday night.

Organised by BTOS Productions, the concert -- titled Netru Indru Nalai -- will celebrate 25 years of Rahman's musical journey from "Roja" to "Kaatru Veliyidai".

It will also feature names like Benny Dayal, Neeti Mohan, Haricharan, Jonita Gandhi, Ranjit Barot and Javed Ali.

Having already earned over Rs 1500 crore from its theatrical release so far, the film is continuing its golden run.

"To Rajamouli, Keeravani and the whole team of 'Baahubali 2'. Just finished watching it in Chennai. I hope it crosses Rs 2000 crore and above at the box-office," Rahman wrote on his Facebook page.

He went on to add: "You guys have opened the floodgates for south Indian cinema to the world and given it a new identity."

A story about two warring brothers for the ownership of an ancient kingdom, the film stars Rana Daggubati and Prabhas as the male protagonists.

Rahman will be seen walking the red carpet of the opening night at the Cannes Film Festival, which begins on May 17.

About his Cannes outing this year, Rahman said in a statement: "I'm very excited working on this ambitious project 'Sangamithra'. I am looking forward to joining the team at Cannes."

A Hindi, Tamil and Telugu trilingual, "Sangamithra" stars Shruti Haasan in the title role, while Jayam Ravi and Arya are the chief male protagonists. The film is directed by Sundar C, produced by Thenandal Studios and has Rahman as its music director.
