While "Delhi Belly" is being directed by ad filmmaker-turned-director Abhinay Deo, "Dhobi Ghaat" is the directorial debut of Aamir's wife Kiran Rao.
"It was really nice and easy working with Kiran since we are very good friends since a long time. She is extremely good at her work and is an incredible filmmaker. It's been nothing but a pleasure working with her," Sampath told in an interview here.
"The music of the film is really eclectic and very experimental. I must say that it is very courageous on Kiran's part to incorporate music like this in her film," he added.
Sampath, who was in the city to launch MTV's new reality show "Kurkure Desi Beats Rock On With MTV", has earlier composed music for films like "Family" and "Khakee". Apart from that he has worked on various music albums and jingles.
Talking about "Delhi Belly" starring Imran Khan, the 33-year-old said: "As far as 'Delhi Belly' is concerned, it is a film that showcases the humorous side of realities of living in India. It is a very interesting film.
"The music of the film is nothing but insane. We have Bhojpuri punk and some very adventurous tracks in the album. At the same time the music is earthy and true to India."
When asked about his experience of working with Aamir, the composer said that it was a dream working with him.
"When I had my first meeting with Aamir for the film, he asked me what kind of music I wanted to create. I said I want it to be as insane as possible.
"Then next we met when the first song for the film was composed. Aamir was there with a lot of other producers. When I played the song, all the producers closed their ears and all I could see on Aamir's face was a smile. I thought he hated the song, but I was surprised when he said that the track was just fantastic," said Sampath.
The composer also claims that the best part about working with Aamir's production house is that there are no deadlines.
"There are no deadlines. They just want you to get it right. They don't want to confine you in deadlines and just want that you work on the song till the time you are satisfied. Aamir and Kiran are just splendid people to work with."
