Gang Signs & Prayer is the debut studio album by British rapper Stormzy. It was released on 24 February 2017 independently through #Merky Records while being distributed by ADA of Warner Music Group. It is Stormzy's first major commercial release, following the Dreamers Disease EP (2014). The album features guest appearances from fellow MCs Wretch 32, Ghetts and J Hus, along with singers Kehlani, Raleigh Ritchie and MNEK. It features production from Fraser T. Smith and Sir Spyro, among others.
 
After gaining attention on the UK underground music scene via his Wicked Skengman series of freestyles over classic grime beats, Stormzy released his debut EP Dreamers Disease independently in July 2014. In September 2015, he released a final instalment to his "WickedSkengMan" freestyle series, "WickedSkengMan 4", onto iTunes. After a year's hiatus from social media to focus on the recording of the album, Stormzy returned in early February 2017 via a series of advertising hoarding campaigns across London displaying lyrical quotes and the hashtag #GSAP 24.02. Gang Signs & Prayer was supported by the lead single "Big for Your Boots".
 
Gang Signs & Prayer received critical acclaim upon release, and entered the UK Albums Chart at number one with sales of over 68,000 copies, becoming the first grime album in history to reach number one. It also charted in twelve other countries. Gang Signs & Prayer holds the distinction of having every song from the album appear concurrently in the UK Singles Chart, including seven songs in the top 40. The album is certified Platinum by the British Phonographic Industry (BPI). Gang Signs & Prayer won British Album of the Year at the 2018 Brit Awards.
