"Pressure" is Nadia Ali's sixth single as a lead artist. It was written by Ali and produced by American DJ Nick Terranova and Italian DJ Alessandro Bacci. Ali and Terranova met in 2009 when Ali requested him to remix her single "Love Story". After that, the two decided to collaborate on original productions and had studio sessions on Christmas Eve '2009 and produced a number of songs, of which one was "Pressure". Ali described "Pressure" as 'a fun song venting about the frustrations and expectations which come with being successful'. The song was left untouched until March 2010, when at the Winter Music Conference Ali introduced Terranova to Bacci, who was subsequently asked to collaborate with the two and co-produce the track creating the final version.
A music video for "Pressure", directed by Brando Neverland was uploaded on YouTube on July 7, 2011. The music video was set to the Alesso remix and features Ali facing different forms of pressure such as a wind tunnel with chains, climbing a very long ladder while being chased by Terranova and Bacci. At the beginning of the video, Nocturne in E-flat major by Frédéric Chopin can be heard, and the building structures shown are those of Utah Valley University's computer science building interior.
The Alesso remix of "Pressure" became a club and festival anthem during summer 2011 and was included in their sets by prominent DJs such as Armin van Buuren, Tiesto, Kaskade, Calvin Harris and Swedish House Mafia. The song was described by Kaskade as the "Tune of 2011". The remix was also nominated for the Best Progressive Track at the 27th International Dance Music Awards at the Winter Music Conference. The song was also remixed by Calvin West, Clocx, Rene Amesz, as well as Matan Caspi & Eddy Good
