Kishore Kumar was an Indian playback singer, musician and actor. He is widely regarded as one of the greatest, most influential and dynamic singers in the history of modern Indian music. Kumar was one of the most popular singers in the Indian subcontinent, notable for his yodelling and ability to sing songs in different voices. He used to sing in different genres but some of his rare compositions, considered classics, were lost in time.
Besides Hindi, he sang in many other Indian languages, including Bengali, Marathi, Assamese, Gujarati, Kannada, Bhojpuri, Malayalam, Odia and Urdu. He also released a few non-film albums in multiple languages, especially in Bengali, which are noted as all-time classics. According to his brother and legendary actor Ashok Kumar, Kishore Kumar was successful as a singer because his "voice hits the mike, straight, at its most sensitive point".
Kumar was also active in acting too. His first film appearance was in Shikari, in which his brother, Ashok played the lead role. Kumar played his first lead in the Bombay Talkies film Andolan. Although he got some acting assignments with the help of his brother, he was more interested in becoming a singer.
