The band is currently composed of Rupam Islam (lead vocals, lyricist), Deep Ghosh (guitar, backing vocals), Allan Ao (guitar, backing vocals), Chandra Biswas (bass, backing vocals), and Tanmoy (drums, percussion).
Their music is flavoured by a blend of blues, hard rock, alternative rock, and psychedelia, along with Rupam Islam’s vocal renditions of his characteristic psychoanalytical lyrics. They are noted for their social commentary and advocation of causes such as the welfare of HIV positive people.Like most other Bangla bands, Fossils performs in the Bengali language.
Formation and early years: 1998 – 2000
The band was formed by Rupam Islam. Their first stage show was held on the 9th of January 1999 at Najrul Mancha for Gaan 99 organised by HMV. This show had Deep on acoustic guitar, Sayantan Bumba on guitars, Tanmoy on bass, Rajiv on drums and Rupam. This line up was short lived and the very next show saw Chandra and Teno on guitars, Baji on drums, bumpy on bass, Jatu on keyboards and Rupam.
The group started to call themselves “Fossils” after a suggestion by their guitarist Deep. The name is inspired by a line from one of Rupam’s lyrics: “Khoro aamar fossil, onubhutir michhil protikriashil kono biplobe”.
Initial audience reaction to the band’s music was not encouraging. During their first few shows, they met with jeering and hostile objection to the rock style and techniques they employed.
Thus, the band name was meant to convey a sense of an “underground” movement that the members felt they had initiated and their belief that they would be fossilized into history under the pressure of social disapproval of their music, only to be excavated decades later by musicologists wishing to discover the roots of Bangla rock.
The band would experience a flurry of lineup changes until the end of 1999, by which time a sort of permanency was achieved with Rupam (vocals), Chandra (bass), Allan (guitar), Stephen (drums), Indra (keyboards), and Parikhshit (manager) as the members.
 Fossils: 2000 – 2003
In 2000, the band recorded a demo version of their tracks. They faced rejection several times from different record houses.
In 2001, the guitarist Allan left the band for a corporate career ( Allan is now back agin with Fossils). Former members Teno and Deep re-joined in Allan’s stead.
A contract was landed with Asha Audio and by the end of the same year, recording for the band’s first studio album began. The recording had to start without Allan, whose departure was so sudden there wasn’t enough time to rework their tracks. Some of the guitar tracks for this album had to be lifted from the demo version. The album was entitled Fossils and released in 2002. It was not an instant success, but the music caught on once the FM radio stations started broadcasting the tracks. The album’s popularity has increased with time.
Teno left the band in 2002 and was replaced by Partha.In 2003, the drummer Stephen underwent rehabilitation. Andre served as part-time drummer till Bubun joined.By this time, the band had created a niche audience and dedicated following among the youth.
Fossils 2: 2004 – 2005
The band’s second album, entitled Fossils 2, was released in 2004. It was then noted as the Bangla band album with the highest budget to date. The album was partly sponsored by the Thums Up brand. The mastering engineer was Steve Fallone of Sterling Sound, New York.The band witnessed a surge in popularity.
In 2005, the manager Parikshit was expelled from the band; Rupam and Deep jointly took over his work. As of 2010, management is handled by Rupam’s wife Rupsha Dasgupta and Deep.
Mission F: 2006
The band’s third studio album, entitled Mission F, was released in 2006. It was a theme album for the first Kolkata Police Friendship Cup Football Tournament.
A special track, “Aeka Nauo”, dedicated to HIV positive people, was included in the album. It featured Usha Uthup and was produced in collaboration with the Kolkata Sukriti Foundation. A free VCD distributed with the album contains the music video for the track, which shows HIV positive people with their faces uncovered interacting freely with Uthup and the band members. The VCD also contained a chat session with band members.Radio Mirchi collaborated with the band to produce two “unplugged” versions of previously recorded tracks that were included in the album.
According to a survey conducted by Radio Mirchi, Mission F was declared the best-selling album in Kolkata for the year 2006.
They performed a Bangla version of the popular Michael Jackson song Earth Song on the occasion of Earth Day exclusively on the news channel CNN IBN.
In the first half of 2007, Rupam Islam worked on a separate project named RnB with the bassist Bumpy.
In the second half of 2007, the band released a music video album entitled Aupodartho.
The album was scheduled to be launched in Music World, Park Street, Kolkata. The crowd turnout was so unexpectedly huge that fans had to be turned out and the outlet’s premises closed. The police had a tough time controlling the crowd. The release eventually happened on the same day, with Rupam Islam placing himself atop a stool outside the outlet and addressing the fans without a microphone.During the Pujas of 2007, Rupam Islam’s 1998 solo album was re-launched by Sa Re Ga Ma HMV.
