He began playing guitar for All India Radio in solo, duet, trio and orchestral settings in 1951 while still a boy.

Even at that early age, Barun's fascination towards the Hawaiian Guitar led to his lifelong single minded dedication towards his Instrument. He made some basic changes to the instrument by adding plucked strings (known as Chikari) and sympathetic strings (known as Tarab). He also pioneered a series of structural changes to make this instrument amenable to the depths and tonal qualities of Indian Classical Music. The development of this instrument has been a passionate and continuous process for Barun over three decades.
