Steel Banglez will collaborate with composer Pritam on the music of the film, directed by Ayan Mukerji.
"I was in Mumbai in January, where I met Ayan Mukerji and Pritam. I am collaborating with them for 'Brahmastra'," the record producer told in a telephonic interview, about his Bollywood debut.
"I was approached by Ayan's team. They wanted some futuristic music. It's still in the works, so I can't say much," he said.
Born Pahuldip Singh Sandhu in 1987, the London-based musician became popular as Steel Banglez a name coined by his Jamaican friend due to his Kara one of the five Ks of Sikhism. He is popular for his production work with artistes including Mist, MoStack and AJ Tracey, and his tracks such as "Bad" and "Fashion week" made it to the UK Singles Chart.
He is in no rush to take up multiple Bollywood projects.
"I think working with Pritam on one of the most anticipated films gives me a good space in India. I haven't taken up any other work (in Bollywood). Also, I am very loyal to Ayan's vision. It would have been disrespectful had I done some other work," he said.
He got to meet megastar Amitabh Bachchan and spend time with Ayan. "It was good," said Banglez, of the experience, although he isn't quite impressed with the way people work in Bollywood.
"I think the way they approach music in Bollywood is so different from the UK. There are different methods. I write music from the scratch, sit there and make music. In Bollywood, they have songs already ready to go, and you pick songs. For me, it's less emotional and it's like a factory," said Banglez, who also has an EP on the way.
He has more plans for India.
"I want to open an orphanage and some schools. My mum always asked me if I wanted to get married. I said no. She said you need to have kids. I said there are enough kids already for me to have. It felt like I have a responsibility," said the record producer, who did jail time for possession of a firearm when he was a teenager.
The prison stint didn't leave a negative impact on him.
"I see that as part of my journey for me to become who I am, the way I think. That quiet time gave me access to knowledge and meditation, and helped me open my third eye. I became spiritual and studied music. It was a blessing because I had the experience of being away from the real world for three years and develop my skills. I thought of myself as a superhero."
