Pandit Kashalkar was born in Nagpur. He received his first lessons in music from his father N D Kashalkar, a lawyer by profession and a noted amateur vocalist and musicologist. He went on to study music at Nagpur University, topping his post-graduate class. Around that time, he trained under Rajabhau Kogje and P N Khardenavis. He initially worked as a programme executive at the Thane station of All India Radio. In 1993 he became a Guru at the ITC Sangeet Research Academy, where he remains today.
Indian music is contoured heavily by its pedagogic tradition of Guru Shishya parampara. An examination of an artiste's musical lineage often yields rich insights into his musical style and personality. Kashalkar studied principally under Pandit Ram Marathe and Pandit Gajananrao Joshi.
Ram (Ramchandra Purshottam) Marathe (1924-1989), popularly referred to as "Rambhau", was a vocalist in the Gwalior tradition. He was a disciple of Mirashibuwa, who in turn studied under the legendary Balakrishnabuwa Ichalkaranjikar, a key figure in the history of the Gwalior Gharana. Pandit Marathe also trained in the Agra style for fifteen years under Jagannathbua Purohit. That apart, he was a prominent actor and music director in the Marathi stage.
Gajananrao Joshi (1910-1987) was an extraordinary figure in the annals of Hindustani music. His father Anant Manohar Joshi was a prominent vocalist and a direct disciple of Balakrishnabuwa Ichalkaranjikar of Gwalior. Gajananrao learnt from his father for many years. However, in a step almost unprecedented for the son of a renowned musician, he also trained under notables of other gharanas, such as Vilayat Hussain Khan of Agra and Manji Khan of Jaipur. Even more extraordinarily, he taught himself the violin (reportedly at the behest of the ruler of Aundh, a princely state he was employed in). Kashalkar undertook a long period of tutelage under him. Indeed, most characteristic features of his style can be traced to Gajananrao's vocalism.
Ulhas is a fabulous vocalist, still in his middle years and young, who has an old musical head stuffed with innumerable current and rare ragas and compositions. Like a computer he never errs in any raga or composition howsoever intertwined or tricky it may be. He, just seems to press one key and out comes a raga in the true Jaipur colours, another to obtain a melody attired in the Agra style and still another to get a raga in the Gwalior habiliments. One can only imagine Kashalkar's questionless loyalty to his various gurus, and his own prodigious capacity to assimilate and consolidate the incoming knowledge.
