Roopkumar is the son of the late Pandit Chaturbhuj Rathod, the classical luminary – an exponent of the rare and arguably the oldest style of singing i.e. Dhrupad.
He belonged to the “Aditya Gharana of Jamnagar”. Pandit Rathod has trained and groomed many well known names like Kalyanji – Anandji, Manhar Udhas and many more. He is famous throughout Bollywood as an excellent playback singer, music director having also performed extensively with Anup Jalota as a percussionist. Roopkumar has two brothers, music composer Shravan Rathod and singer Vinod Rathod. He is married to Sunali Rathod.
The song "Sandese Aate Hai", from the movie ‘Border’, became one of the major breakthroughs of Roop Kumar’s career. It soared to an unprecedented level of popularity, becoming an anthem of sorts for the nation. Riding on this wave of popularity and tirelessly pursuing his passion for music, Roop Kumar lent his voice to a number of songs in Gujrati, Hindi, Marathi, Tamil, Telugu, Bengali, Oriya, Assamese and Bhojpuri films. Apart from playback singing for films, Roop Kumar’s other thrust of interest is live concerts. With his equally gifted wife Sunali Rathod, he travels all over the world and performs at a number of concerts. Together, they have enchanted audiences across countries like USA, UK, Dubai, East Africa, Singapore, etc. with their soulful renditions of various genres of music spanning ghazal, sufi, light classical and film songs. Roop Kumar also performs live-on-stage, with artists like Trilok Gurtu, Ranjit Barot and Abhijeet Pohankar in fusion concerts.
He has collaborated with Trilok Gurtu for a fusion based album, ‘Beat Of Love’, released in December 2001 and a jazz based album, ‘Broken Rhythms’, released in October 2004. In August 2005, the popular comedy serial Sarabhai vs. Sarabhai featured Roop Kumar and Sunali Rathod in one of their episodes that showcased a friendly musical contest. Roop Kumar, along with wife Sunali, added another feather to his cap by together winning the coveted title of ‘Ustaad Jodi’ on ‘Mission Ustaad’, a much acclaimed musical television reality show aired in February 2008, that aimed to create awareness about social causes. He recently released a sufi album along with Sunali Rathod called Kalmaa. He sang title track of Gujarati movie Kevi Rite Jaish in 2012.
