[5] Arunendu was a member of the scout group of Bhowanipur Mitra Institution (Kolkata), and traveled with them on a camping trip to Puri (Orissa) in the summer of 1955.

Arunendu introduced to the formal rudiments of music and the techniques of playing the steel guitar by his school friend Prabir Kumar Das.

Most of his songs were personal in nature and were composed primarily to exercise his newly acquired knowledge about the chords on a steel guitar and to sing to his close circle of friends.

At this time Arunendu also started to dabble in classical Spanish guitar, not then an easily available option in Kolkata with its usage restricted to the pubs of the Park Street area and certain members of the Anglo-Indian community.

Joining the folk club of the market town of Bicester in Oxfordshire where he lived and was practicing as an architect, he picked up certain guitar techniques from the resident and guest artists who performed there.

Arunendu's songs were never intended for a wider audience and this remained the case until one day Gautam Chattopadhyay paid a visit to his residence in Moore Avenue (Kolkata) in early 1987.

During the release of their first come-back album "Aabaar Bochhor Kuri Pore" (1995), the accompanying brochure of the same name mentioned about Arunendu as a predecessor of Mohiner Ghoraguli.
