After DEB had a stammer in his childhood, his grandmother sent him to singing lessons at the age of 5, where he learned classical vocals till he was 15 years. It’s Rabindra Sangeet that cured his stammering. Before entering the industry, he was selected as a lead singer of Mirage, a rock band in kolkata, India. Mirage gained popularity in school and college circuits and performed for MTV, Doordarshan, etc. DEB left Mirage to collaborate and formed ‘The Lost’ with Arkopravo Mukherjee and Rahul Guha Roy (Cassinni’s Division). In July 2008, Arko & DEB showed some songs to Achille Forler, the Frenchman who pioneered music publishing in the country and had partnered with Universal Music Publishing. He signed the duo as songwriters and produced their 11-track album Mira, for which they co-wrote the music and the lyrics. As the album was about to be released, Arko left as he got another project and thus, Mira could not be completed. His music publisher gave him a small job that helped to pay his bills and pushed him back into the studio under the stewardship of ace sound engineer, Devashish Ray, nephew of Pandit Hariprasad Chaurasia. The first video was a ballad in his native Bengali, Phiriye De. The following year he revisited a song from his first album Mira on a single acoustic piano. Ore Piya, in a video that sums up his situation in those days.
