Explanation:

Ustad Amir Khan (15 August 1912 – 13 February 1974) was a well-known Indian classical vocalist. He is considered one of the most influential figures in Hindustani classical music, and the founder of the Indore gharana. Amir Khan was a virtually self-taught musician. He developed his own gayaki (singing style), influenced by the styles of Abdul Waheed Khan (vilambit tempo), Rajab Ali Khan (taans) and Aman Ali Khan (merukhand). This unique style, known as the Indore Gharana, blends the spiritual flavour and grandeur of dhrupad with the ornate vividness of khyal. The style he evolved was a unique fusion of intellect and emotion, of technique and temperament, of talent and imagination. Unlike other artists he never made any concessions to popular tastes, but always stuck to his pure, almost puritanical, highbrow style.
