Fossils came to be at a time when Bangla rock was taking its baby footsteps. The little work that was happening in the genre of rock music was limited to ‘one off' songs amongst many. No constructive effort was made to establish the genre of rock in the Bangla music scenario. Fossils burst onto this scene and changed it. Rupam Islam, after his debut solo album launched in 1998, went on to form Fossils a year later, with a handful of musical colleagues who shared his vision of a band that would push the envelope of contemporary Bengali rock. Many consider Fossils to be the pioneers of Bangla rock. Fossils’ first album (2002) also saw the term 'rock' being mentioned as a genre for the first time in any Bangla album. With the popularity of Fossils’ songs, West Bengal witnessed a sea-change in the Bangla music scene, especially the Bangla band scene. All new upcoming bands who till then were working mainly in the genre of Bangla folk suddenly took to Bangla rock, and Bangla rock became the most popular form of music amongst the youth. Within a short span of four years, Fossils went on to become the most popular Bangla band in India, largely due to its explosive LIVE shows and introspective and cathartic lyrics with melodic aggression, pushed forth further by the release of their second album, Fossils 2, in 2004. The band is equally popular with non-resident Bengali audiences across the globe, whether in Bangalore or Mumbai, Hyderabad or Houston. Fossils has two successful UK shows, two USA (Banga Sammelan) tours, one Australia show and many shows in neighboring Bangladesh under its belt.
