Classicool features a group of musicians who collaborate to create shorter, more accessible versions of traditional ragas, incorporating elements like bass and drums. Classicool has been described as a contemporary interpretation of classical and fusion music in India, with Purbayan Chatterjee at the helm.

The band includes other talented musicians and has performed at various events, showcasing a unique blend of instruments such as the sitar, tabla, keyboard, violin, and percussion. The project has also involved collaborations with other artists, such as U Rajesh, in a musical collaboration named "Milaap," which blends classical and Carnatic music.
