He got his first break in the Bollywood films from the music director Himesh Reshammiya. After listening to his voice, Himesh Reshammiya signed him to sing the song 'Desi Beats' in Salman Khan Starrer 'Bodyguard' released in 2011
Alamgir Khan shot to instant fame with his song 'Mauka Mauka', a musical campaign launched by ICC Cricket World Cup in 2015. He was approached by the production house Bubblewrap Films as the song required a singer who could do justice to an Alaap and a Sufi tune with equal ease. Initially, he refused the song thinking that he had to lend his voice for the Pakistan Cricket Team. After his friend the campaign music director Rohan Utpat convinced him that the song was to be sung for the Indian Cricket Team, he agreed.
