Nadeem–Shravan were an Indian music directors duo in the Bollywood film industry of India. They derives its name from their first names as, Nadeem Akhtar Saifi (born 6 August 1954) and Shravan Kumar Rathod (13 November 1954 – 22 April 2021). Nadeem–Shravan were the most successful Bollywood music directors of the 1990s until the early 2000s. They displayed a strong influence of Hindustani (classical / semi-classical) music in their compositions, and were the only composers during the 1990s and 2000s who relied heavily on three particular instruments: the bansuri, the sitar and the shehnai in almost all of their songs. By using these instruments in a modern way without disconnecting them from their original value, their contribution is unique compared to some rising music directors evolving a new music style beginning in the mid-1990s. They are considered one of the most successful and greatest music composers in Hindi cinema history. Their breakthrough soundtrack album was Aashiqui (1990), which sold 20 million units in India, and became the best-selling Bollywood soundtrack album of all time. Nadeem–Shravan were also behind many of the other best-selling Bollywood soundtrack albums of the 1990s. Their success helped establish the music label T-Series. The duo's career temporarily came to a halt with the murder of T-Series founder Gulshan Kumar by Mumbai underworld syndicate D-Company, with Nadeem Akhtar Saifi initially accused of involvement, before later being exonerated. The duo eventually made a comeback in the 2000s. Nadeem–Shravan composed soundtracks for many Hindi films, including Aashiqui (1990), Saajan (1991), Phool Aur Kaante (1991), Sadak (1991), Deewana (1992), Dil Hai Ke Manta Nahin (1992), Dil Ka Kya Kasoor (1992), Sapne Sajan Ke (1992), Damini (1993), Hum Hain Rahi Pyar Ke (1993), Rang (1993), Dilwale (1994), Aatish: Feel the Fire (1994), Salaami (1994), Raja (1995), Barsaat (1995), Agni Sakshi (1996), Jeet (1996), Raja Hindustani (1996), Pardes (1997), Judaai (1997), Naseeb (1998), Maharaja (1998), Aa Ab Laut Chalen (1999), Sirf Tum (1999), Dhadkan (2000), Kasoor (2000), Hum Ho Gaye Aapke (2001), Yeh Dil Aashiqanaa (2001), Raaz (2002), Dil Hai Tumhaara (2002), Dil Ka Rishta (2003), Andaaz (2003), Qayamat: City Under Threat (2003), Tumsa Nahi Dekha (2004) and Bewafaa (2005), among others.
