Bachchu was born on 16 August 1962 to a Bengali family of Muslim Chowdhuries in Khorna, Patiya, Chittagong District, East Pakistan. He was the son of Mohammad Ishaque Chowdhury and Nurjahan Begum. The family moved to Chittagong city after the Liberation War of Bangladesh in 1971. They resided in Jubilee Road. He had two brothers and was the eldest among them all. His daak naam was Robin. He got his first acoustic guitar from his father as a gift in 1973, when he was in class six. He learned to play guitar from Jacob Dias (the founder of "Spider" band), who used to live in Chittagong. "Spider" band is the first band of Chittagong. From 1974 to 1977 he was playing guitar in Spider band and then he made his own band Ugly Boyz. He borrowed an electric guitar from his friend, Kumar Bishwajit, which was a Teisco Guitar. Bishwajit gave him the guitar after he [Bachchu] showed more interest towards it. He was very attracted to the guitar playing techniques of Jimi Hendrix and Joe Satriani. He was admitted to Government Muslim High School in 1975. In 1979, he graduated from Muslim High School. His parents did not support him on becoming a musician. But, after his family saw his passion for rock music, they agreed on letting him become a musician. While studying in high school, Bachchu formed a band named "Golden Boys", which was later renamed as "Ugly Boys". Kumar Bishwajit was the lead singer of the band and Bachchu was the guitarist. They used to do club shows and shows in weddings (Mostly in the Patiya Upazilla). The group disbanded after Bachchu joined Souls in 1980.

While working with his own band Ugly Boys, Bachchu joined the rock band Feelings (now known as Nagar Baul) in 1977. Feelings' frontman James stated that he saw Bachchu playing guitar at a tea stall. He was amazed by the playing style of Bachchu and he asked him to join the band. In the mid-1977, he joined the band as the lead guitarist and only stayed with the band for next two years until in 1980, he got a contract from Souls, as their lead guitarist Sajed ul Alam had left the band for the United States. Bachchu was playing with Feelings in a club in Chittagong, where Souls' keyboardist Naquib Khan was present. He was amazed by the playing of Bachchu and he talked to lead singer Tapan Chowdhury about it. Both of them saw Bachchu playing in the club next day and they asked him to join Souls. He joined Souls in early-1980 and played with the band for next 10 years as the lead guitarist, songwriter and occasional singer. He had appeared on three studio albums College Er Corridore (1985), Manush Matir Kachakachi (1987) and East and West (1988). In the late-1990, Bachchu left Souls and went on to form his own band Little River Band, which later became famous as Love Runs Blind. He reunited with Souls in several reunion shows and has performed with members of the band like Tapan Chowdhury, Kumar Bishwajit and Naquib Khan in several shows. In 2012, Bachchu told The Daily Star that:

I left Souls because of two different tastes in sounds. They liked one kind of music, I liked another. I was into loud, rocking, powerful sounds, and the rest of the members wanted quiet, melodious sounds. You cannot just compromise day after day. We never really had any big arguments, but it occurred to me that it would be better if I just quit and do something different.

After Bachchu got out of Souls in the late-1990, he came to Dhaka in 1991 and in January he married Ferdous Chandana, with whom he had a relationship since 1986. He formed a band named Yellow River Band on 5 April 1991 with Saidul Hasan Swapan on bass guitars, S.I. Tutul on keyboards and Habib Anwar Joy on drums. When they were performing in a club in the mid-1991, they were mistakenly called the Little River Band, which Bachchu liked and officially named his band. But, after they heard about the Australian rock band of the same name they changed their name to Love Runs Blind in 1997. In April 1991, LRB did their first ever concert in the University of Dhaka, a concert that was arranged by BAMBA, celebrating the downfall of autocratic leader Hussein Muhammad Ershad. In January 1992, they released the first ever double album: LRB I and LRB II. The band's third studio album Shukh, was released in June 1993. It included "Cholo Bodle Jai", which regarded by some as Bachchu's greatest work. They released several albums in the 1990s and soon became one of the most popular rock acts of Bangladesh. In 1996, they performed in Bengaluru, which was their first concert outside Bangladesh. LRB is the only Bangladeshi artist to perform in the Madison Square Garden in New York City. In 2018, LRB got disbanded after Bachchu's death.
