From May 2009 to 2014, he was a member of parliament of India in the 15th Lok Sabha, having been elected from the Jadavpur constituency in West Bengal, from Trinamool Congress.

Suman was born in a Bengali Hindu Brahmin family on 16 March 1949 to Sudhindranath and Uma Chattopadhyay at Cuttack, Odisha.

Thinking thus, he went to West Germany again in September 1986, and before departure he recorded another album of 'Nagarik', following the procedure just written before, but this time in the new studio he constructed.

During this time he felt that guitar is a simple instrument, which could be played by a solo musician, and there is no question about any type of multi-instrument orchestra.

He sang "Tin Shataker Shahar" with guitar, then "Tomake Chai" and finally "Amader Janya" – both with electronic keyboard.

[8] He started to practise his voice with the help of electronic tanpura, continued keyboard and guitar playing, and also creating songs with some contemporary incidents.

Tarun Majumder listened to some of his songs, and selected "Pratham Sabkichhu" to use in one of his upcoming films 'Abhimane Anurage', although he requested Suman to change some of his lyrics to match with the theme of that movie.

Ravi Kichlu, the head of the product development division of that company welcomed Suman, and showed interest to record his songs.

It was the first Bengali Basic Song Album which was entirely written, composed, sung and musical instruments played by the artist himself.

His contemporary urban, socially conscious songs draw upon both Bengali adhunik (modern) and Western folk and protest music.

[citation needed] He released his first solo album, Tomake Chai, on 23 April 1992, which was immensely successful as it redefined Bengali songs.

The title song 'Jaatishwar' inspired then young Srijit Mukherjee, and he made a Bengali feature film with the same name in 2013.

In this year, he wrote, composed, sung, and even played a cameo role in a Bengali film Mahasangram, which contained 6 songs.

Amit Bandopadhyay arranged the instrumental music with many session musicians for all songs but one, where Suman played his guitar and harmonica only.

Unlike Mahasangram, Suman played all instruments like electronic keyboard, guitar and harmonica and himself was an arranger like his basic albums.

One of Suman's greatest critical success, was his concert at Kalamandir in Kolkata with American folk icon Pete Seeger, in 1996.

[11] After a long gap throughout 2000, Kabir Suman returned to recording career again in January 2001, by publishing his 10th album 'Jabo Awchenay', which contained 10 songs.

It was the first Bengali album which contained songs that were written, composed, sung, instruments played, recorded, mixed and mastered by a single person.

All songs' theme was mysterious death of young multimedia designer Rizwanur Rahman, which was very controversial, and created some political unrest in West Bengal.

Like 'Nandigram', all songs' theme was forceful land acquisition from then state government, and brutal massacre by them, and the royalty of this album went completely to those ordinary persons of Singur and Nandigram, Both 'Nandigram' and 'Protirodh' became very popular to the then opposition party of West Bengal All India Trinamool Congress.

The main theme of this album was the forest area at western West Bengal, its people, their political situation, and some reasonless harassment from central government.

Like 'Chhatradharer Gan', all songs were in favor of revolution of forest people living in western West Bengal, and protest against harassment caused by the central paramilitary force, operation Green hunt etc.

A very sharp ear can listen a humming sound in the end of some songs, it was due to 14 Kilohertz crosstalk signaling.

[clarification needed]Since 2006, when Suman was involved in the land struggle in Nandigram, he started aligning himself to Trinamool Congress.

He converted to Islam in 1999 to mark his protest against the killing of Christian missionary Graham Staines by a former member of Bajrang Dal.

"[27] Suman supported a ban by the Government of West Bengal on the book Dwikhandito, written by the Bangladeshi writer and activist Taslima Nasrin, for allegedly blaspheming the Prophet Mohammed.

[28] Academic Malvika Maheshwari has linked Suman's initial candidature by the Trinamool Congress with his support for the ban on Nasrin's book, as part of a "policy of 'Muslim appeasement'" by the party.

Suman's conduct was widely criticised and led to a criminal complaint being filed against him for attacking Hindu sentiments and misogynistic vulgar statements about women in West Bengal.

[31][32] Since 2011, many old and new songs are publishing in his website and Facebook [with Nachiketa Chakravarty, Anjan Dutt, Indrani Sen, Lopamudra Mitra, Payel Kar, Shalini Chatterjee, Sreetoma Ghosh, Shayari Das, Tanushree Haldar, Paromita Chatterjee, Reema Roy, Shubhanwita Guha and Reetomaa Gupto (All Composition: Kabir Suman)]
