Kalyanji and Anandji were children of a businessman who migrated from Kutch to Mumbai to start a grocery and provision store.The brothers began to learn music from a music teacher, who taught them in lieu of paying his bills to their father.
One of their great-grandparents was a folk musician of some eminence.
They spent most of their formative years in the hamlet of Girgaum (a district in Mumbai) amidst Marathi and Gujarati environs and among some eminent musical talent that resided in the vicinity.
Kalyanji started his career as a musician, with a new electronic instrument called the clavioline. which was used for the famous "Nagin Been," used in the film Nagin (1954) which had the music of Hemant Kumar.
Kalyanji then, with his brother Anandji, started an orchestral group called Kalyanji Virji and Party which organised musical shows in Mumbai and outside. This was the first attempt made for holding live musical shows in India. more info
