In 1999, there was another children song album 'Eksathe Banchboi' with 12 songs. Unlike 'Chhoto Boro Miley', here no other famous singers sang. All songs were sung by child singers, although they were not same of those in 'Chhoto Boro Miley' (except Payel Kar, who was in both albums). Also in this album, all songs were accompanied with electronic keyboard, and hardware drum programmer by Suman. Suman used both instruments very complexly, and created an ethereal orchestration alone. He also sang 3 songs collaboratively with those child singers, and he says that it was his best artistic work till now. In this year, another album published named 'Achena Chhuti', which contained 14 songs, where Suman sang with Sabina Yasmin. Some songs were sung by Suman, some by Sabina, and some as duet. The entire instrumentation was done by Suman. Only two songs were accompanied with guitar and harmonica, rest of the songs were accompanied completely with electronic keyboard, and sometimes with harmonica, like 'Nishiddha Istehar'. It was his first basic song album, where complete lyrics of the songs were printed in its album cover. It was his last collaborative album as 'Suman Chatterjee'. Initially it was published only as cassette, but later also as CD. It was his first album which was published from a recording company other than SAREGAMA India Limited; it was published from Raga Music. Motion picture soundtrack In 1994, Kabir Suman debuted his Soundtrack music career. 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. Here Suman sang with Indrani Sen. Some songs were sung by Suman, some by Indrani, and some as duet. Background score was also done by Suman. Unfortunately the motion picture released after a long 12 years gap, in 2006, and was flop. In 1997, Suman became music director again in a Bengali film Sedin Chaitramas, which contained 7 songs. Unlike Mahasangram, Suman played all instruments like electronic keyboard, guitar and harmonica and himself was an arranger like his basic albums. It was his first soundtrack where he worked with own instruments. Beside Suman, other singers in this album were Nachiketa Chakrabarty, Lopamudra Mitra & Swagata Lakshmi Das Gupta. Background score was also done by Suman.
