Following his debut as a music director in Hindi films with Prarthana (1969), the next film for which Hridaynath Mangeshkar composed for was Harishchandra Taramati (1970). It is here is the song sung by Lata Mangeshkar Raja Beta Soya Mera, a rare song where Lata expresses
sadness more explicitly that her usual subtle style.an interesting soundtrack if only for the simple reason that it is unlike the unconventional and complex compositions one would normally associate him with, almost as if he was trying hard to fit within the prevalent templates of Hindi film music of those days. Very heavy on orchestration, most of the songs are as conventional as can be. One can find some of his trademark twists in the songs, but they are few and far between. Two noteworthy features of this soundtrack, if only for the sake of trivia, that it includes the only songs Mohd. Rafi sang for Hridaynath and also the only Hindi film song with four Mangeshkars associated with it.
