Australian filmmaker Baz Luhrmann congratulated good friend A.R. Rahman on winning a double Grammy and praised the music maestro as "amazing".

"Congratulations A.R. He is amazing and now he has won two Grammys. To think that only a couple of days ago, we were sitting together and discussing our children and what we love (in terms of creative sensibilities) is like a dream, " Luhrmann told here.

"We are friends. Whenever he is in my country or whenever I am here, we catch up. We discuss whether we should have a live concert or any other collaboration. The relationship is precious, " he added.

Lurhman is not oblivious to Bollywood song and dance culture as he used the popular Hindi song "Chamma chamma" from the film "China Gate" in his musical "Moulin Rouge".

According to reports, the ace director now wants to collaborate with Rahman as he wants to make film in India.

Luhrmann was in the capital Monday with Archibald Prize winner Australian portrait painter Vincent Fantauzzo to paint a 14/5ft public mural called Art Gesture at Le Sutra, Mumbai.

Rahman composed a free-of-cost background music for the video that shows the two artists doing the same. It has been shot by Kaizad Gustad. After finishing that, Luhrmann and Fantauzzo embarked on a Classic Tour on Royal Enfield Classic motorcycles to Rajasthan and painted frescoes there.

They will have an exhibition of photographs taken during their Rajasthan tour and proceeds from it will go to the charity DEEDS.
