Following the decline of disco in the Western world, he later found success in Asia during the 1980s, where he launched the careers of the late Pakistani pop singer Nazia Hassan and her brother Zohaib; he produced their debut album "Disco Deewane", which charted in fourteen countries and became the best-selling Asian pop album up until that time, and helped the duo eventually sell 60 million records worldwide. During that decade, he also produced several hit Bollywood soundtracks for films such as "Qurbani" (1980) as well as several hit songs for Japanese pop idol Akina Nakamori and Chinese pop singer Samantha Lam (林志美). In the 1990s, he popularised Indian pop with the hit album "Made in India" (1995), which became the best-selling pop album in India and launched the career of Alisha Chinai, after which he would launch the careers of several more Indian pop acts such as Shaan and his sister Sagarika as well as Sonu Nigam. In the 2000s, Biddu has been active in the Western and Indian music scenes producing albums which are more spiritual and Eastern-oriented. He rearranged a classical hit for Luke Kenny's film, "Rise of the Zombie".
