Adi Shankara (Sanskrit: आदिशङ्करः Ādi Śaṅkara, pronounced [aːd̪i ɕəŋkəɾə]) (788 CE - 820 CE), also known as Śaṅkara Bhagavatpādācārya and Ādi Śaṅkarācārya was an Indian sage from Kalady in present day Kerala who consolidated the doctrine of advaita vedānta. His teachings are based on the unity of the ātman and brahman— non-dual brahman, in which brahman is viewed as nirguna brahman, brahman without attributes.

Shankara travelled across the Indian subcontinent to propagate his philosophy through discourses and debates with other thinkers. He is reputed to have founded four mathas ("monasteries"), which helped in the historical development, revival and spread of Advaita Vedanta of which he is known as the greatest revivalist. Adi Shankara is believed to be the organizer of the Dashanami monastic order and the founder of the Shanmata tradition of worship.

His works in Sanskrit concern themselves with establishing the doctrine of advaita (nondualism). He also established the importance of monastic life as sanctioned in the Upanishads and Brahma Sutra, in a time when the Mimamsa school established strict ritualism and ridiculed monasticism. Shankara represented his works as elaborating on ideas found in the Upanishads, and he wrote copious commentaries on the Vedic canon (Brahma Sutra, principal upanishads and Bhagavad Gita) in support of his thesis. The main opponent in his work is the Mimamsa school of thought, though he also offers arguments against the views of some other schools like Samkhya and certain schools of Buddhism.

Sonu Nigam (born 30 July 1973 in Faridabad, Haryana, India) is an Indian singer whose songs have been featured in numerous Hindi and Kannada movies, as well as films in Tamil, Assamese, Punjabi, Bengali, Marathi and Telugu. He has also released numerous Indi-pop albums and acted in a few Hindi movies. He had changed the spelling of his last name from 'Nigam' to 'Niigaam' in accordance with numerology, but later returned to the original spelling 'Nigam'.

Sonu Nigam began his singing career at the age of three, when he joined his father on stage to sing Mohammed Rafi's "Kya Hua Tera Vaada, Wo Kasam Wo Irada". From then on Sonu accompanied his father on his singing appearances at weddings and parties. In his teenage years he successfully participated in several music competitions. He moved to Mumbai with his father to begin his Bollywood singing career at the age of 19.

His initial years in Mumbai proved to be a struggle, beginning by singing covers of Mohammed Rafi songs, mainly for a number of Rafi Ki Yaadein albums released by T-Series. T-Series promoter Gulshan Kumar played a key role in identifying Nigam's talent by giving him a chance to reach a larger audience. These albums contributed to T-Series for some years although Nigam's singing style was regarded by some to be like that of a "Rafi clone". Nigam's first movie song as a playback singer was Janam (1990), which was never officially released. He also got a break in radio commercials until he appeared on the popular TV show Sa Re Ga Ma, after which there was no turning back. He was trained by classical singer Ustad Ghulam Mustafa Khan.

Alka Yagnik (born March 20, 1966 in Kolkata, West Bengal, India) is an Indian singer. Among the best-known playback singers of Hindi cinema, she is a record seven-time winner of the Filmfare Award for Best Female Playback Singer from a record of 35 nominations, a two-time recipient of the National Film Award as well as several other music awards listed below. Further, as many as 20 of her tracks feature in BBC's "Top 40 Bollywood Soundtracks of all time" review.

Alka Yagnik was born in Kolkata on March 20, 1966. Her mother Shubha Yagnik was a singer of Indian classical music. She received her school education from Modern High School for Girls. At the age of 6, she started singing for Akashvani (All India Radio), Calcutta. At age 10, her mother brought her to Bombay as a child singer. She was advised to wait until her voice matured, but her mother remained determined. On a subsequent visit, Alka got a letter of introduction to Raj Kapoor from his Kolkata distributor. Kapoor heard the girl and sent her with a letter to noted music director Laxmikant. Impressed, Laxmikant gave her two alternatives — an immediate start as a dubbing artist or a later break as a singer; they settled for the latter.
