"One big artiste, I would like to work with is Pharrell Williams. He is very versatile artist," Kej told PTI.
Bengaluru-based musician Kej said Pharrell was versatile because he makes music in all genres and will be an interesting artiste to work with.
Kej said he would also like to team up with Zimmer, who composed music in 'The Lion King', '12 Years a Slave' and 'Interstellar', because he can infuse Indian element into the American artiste's compositions.
Kej feels the Grammy award has encouraged him to make more non-film music.
"This award has encouraged me to make more non-film music because suddenly winning the biggest music award in the world makes me feel I am doing the right thing of making music from my heart, not from the director's," he said.
However, Kej said he is open to Bollywood.
"If Bollywood wants to use my existing music, I would love to give my existing music to be placed in the films," he said.
