Rajesh Roshan is the son of erstwile Bollywood composer Roshan and brother of film director and Actor Rakesh Roshan. His teacher was Faiyaz Khan. Rajesh Roshan had learnt music at a very young age.
He had a successful association with Basu Chatterjee, Lata Mangeshkar and Kishore Kumar. He shot to fame with the score for Julie (1975 film) for which he won the Filmfare Best Music Director Award. He is the first music director who made superstar Amitabh Bachchan to sing. He usually composes music for the films that his brother either produced or directed.
Rajesh Roshan, like most bollywood music directors, has been accused of frequent plagiarism. On more than two occasions, he has used Vangelis's themes for the soundtrack of his movies without giving credit to him. For example, the soundtrack of Vangelis's 1492: Conquest of Paradise was used throughout the movie of Koyla. Also, Vangelis's theme for Voices was used in the movie Kaho Naa Pyaar Hai. 
Besides Vangelis, he has sampled Kingston Trio's A Hundred Miles, Bond (band)'s Victory , Ceddin Deden's march song for movie Krrish, Bobby Bare's - 500 Miles Away From Home for movie Jurm, Michael Jackson's They Don't Really Care About Us for the movie Koyla and A.R.Rahman's "Mukkala Muqabla" for the movie Raghuveer.
He is also uncle to Hrithik Roshan.
Film making and Bappi Lahiri’s disco music held sway, however even in this period, Rajesh scored a hit with Jaag Utha Insan (1984) and Khoon Bhari Maang (1988).
In the 1990s, when even the mighty Laxmikant-Pyarelal and the doughty Bappi Lahiri gradually lost their bearings, Rajesh has endured through films like Jurm and Bahaar Aane Tak (1990) — and after another dull phase, Karan Arjun and Sabse Bada Khiladi (1995), Papa Kahte Hain (1996), Koyla (1997) and now Laawaris and Daag, both of which climbed the charts. In an era when only a hit film’s score is noticed, Rajesh has also delivered impressive scores in such non-starters as Kaun Sachaa Kaun Jhootha and Dastak (1996), and Dandnayak and Main Solah Baras Ki (1998).
Then came the age of working with his brother Rajesh, who had emerged as a director of great stature. Rajesh had a fixation for the letter K, as he considered it a symbol of good fortune. This proved right in most cases, since most Rakesh Roshan films would have an element of appeal, along with a winner score, courtesy Rajesh Roshan. The two worked on films like Kishan Kanhaiya, King Uncle and the successful "Karan Arjun". The dampener, Koyla, also had some memorable melodies. Rajesh Roshan chose to did not by any means lie low, but he was preparing for "Kaho Naa...Pyaar Hai", the launch vehicle of nephew Hrithik, and one of his brother's most ambitious projects. "Pyaar Hai" achieved significant success. The music of the film is still considered a watershed of sorts, and singer Lucky Ali was introduced into the playback singing fold. The composer also won Film-Fare award for Best Music, thus coming full circle.
Apart for his aversion to publicity, Rajesh is known in the industry for his soft-spoken nature. Laxmikant termed him The Last Of The Originals and Kavita Krishnamurthi terms him the most gentlemanly of all the composers. In his Juhu, Mumbai music room (where his father too composed his unforgettables). Rajesh rewinds and unwinds to Screen across his father’s harmonium which he continues to use.
