Susmit, who along with Asheem Chakravarty had founded the iconic band in 1990, will hand over his legacy to a younger guitar player.
"Right now, I am at my creative best. Indian Ocean is a sound and style we created. After more than 27 years of playing I feel that I am brimming with more compositions, more music - but in a grammar and style that is different from Indian Ocean," Susmit said in a statement.
"So I feel restricted now as I am sure must be the case with the others as well. I strongly believe that my moving on will be beneficial for both Indian Ocean and my creative expression as well," he said.
He is collaborating with a bunch of musicians- Anirban Ghosh, Nikhil Vasudevan, Amit Sharma, Sudhir Rikhari, Rajiv Raja and old friend Gyaan Singh (of Mrigya fame) and creating music with them as 'The Susmit Sen Chronicles'.
Young and upcoming guitarist Nikhil Rao will take over the task of carrying on Susmit's tradition.
"Rao is a promising young guitar player with a lot of Indian-ness in his playing. He will be able to give a lot of impetus to Indian Ocean as he will not only add value to concerts but will also be able to create new music with the band in their signature style," Susmit added.
