Legendry Sufi musician and singer Nusrat Fateh Ali Khan was on Tuesday honoured by search engine giant Google with a doodle marking his 67th birth anniversary. The doodle was exclusive for users from India and Pakistan.

These special days include NASA’s discovery of water on Mars; Mangalyaan’s Mars mission; Pongal; Diwali, and the 2014 general elections of India.

Adding yet another doodle to its list, Google, on Tuesday, replaced its logo with a graphical image of legendary musician Nusrat Fateh Ali Khan on his 67th birth anniversary.

Born in a musical family with a 600-year-old Qawwali tradition, Khan started his career at the age of 16 and went on to perform in 40 countries with various music artistes making him a well-known world music artiste.

Considered as one of the greatest voices ever recorded, Khan also possessed an extraordinary vocal ability and could perform at a high intensity level for a long time. Being a master of classical music, Khan mesmerized the western audience with his vibrant energy, breathtaking stamina, musical genius, captivating voice, and blatant originality.
