Rajat Dholakia, also known as Juku, is a multi-faceted musician and sound designer. He is the son of Dilip Dholakia, a Hindi film music director and singer who was active in the 1950s and 1960s. While Rajat is primarily self-taught, he did learn music from his father and also from Pandit Ramprasad Sharma and French guitarist, Mark Salan.

Rajat has composed music for several plays, documentaries, ad jingles like Thanda Matlab Coca Cola, Pepsi's Yeh Dil Maange More and Aadhar's Yeh Hai Meri Pehchan, and films like "Holi", "Mirch Masala" and "Dharavi" for which he won the National Film Award for Music Direction.

Rajat collaborated with A.R. Rahman on the song "Genda Phool" ("Delhi 6", 2009), bringing in influences of Chattisharhi music into the song.
