Born on January 17, 1984, Calvin Harris was known in Dumfried, Scotland as Adam Richard Wiles. Harris cited that had he had curly hair, he would have been a football player, but fate played different scenario. Harris was first introduced to electronic music in his teens, recording his own demos in his very own bedroom. So occupied was he with his new hobby that he became an anti-social person. However, his hard work paid off when his songs were released by a label in early 2002. "Da Bongos" and "Brighter Days" became his first professional releases.

Harris was discovered on MySpace by Tommy Sunshine who owned Xylophone Jones Recordings. But his big break came in 2006 when he was signed as Sony BMG's artist. His debut album was released in June 2007 under the title "I Created Disco". The effort gathered fans for Harris with the uptempo electronic tracks like "Vegas" and "The Girls". The album reached number eight on the U.K. Albums chart with sales of more than 100,000 copies. Harris then took some time to work on Kylie Minogue's "X" album, producing two of the tracks.

It did not take long for Harris to begin mulling for the sophomore effort. In 2008, he was halfway through completing songs for his new album when he said lost his laptop at London Heathrow Terminal. Harris said he had the only existing copy of his album on the laptop, but later confirmed that he actually did not lose the electronic device. He lied so that he could buy more time to finish the album. "Ready for the Weekend" was completed for release in August 2009. The lead single "I'm Not Alone" went straight to number one on U.K. Singles chart.

In support of his second album, Harris embarked on U.K. and U.S. tours throughout the second half of 2009. His single "Dance wiv Me" was nominated as Best British Single at 2009 BRIT Awards. He was also later nominated for Best British Male at the 2010 BRIT Awards but lost it to Dizzee Rascal. In July 2010, Harris released a mixtape titled "L.E.D. Festival" which was available for free a limited amount of time. Later in 2011, he hit the road as the supporting act of Rihanna in the European leg of her Loud Tour. He was also due to open for Katy Perry but backed out because of production issues and difficulties with Perry's management.

In June 2011, Harris released "Bounce" as the first single of his third studio album. It was followed by "Feel So Close" that became Harris' first solo entry on the Billboard Hot 100 in the U.S., peaking at number twelve. For the new album, Harris collaborated with the likes of Ellie Goulding, Ne-Yo, Rihanna, Kelis and Florence Welch. "Feel So Close" won Best Electronic Video at the 2012 MTV Video Music Awards where he was made the house DJ. Harris also won Video of the Year for his Rihanna-collaborative track "We Found Love" at the awards show. After months of promotional efforts, the album "18 Months" hit the stores October 26, 2012 via Columbia Records.

In 2014, Harris collected his then-highest-charting single on Billboard Hot 100 when "Summer" reached No. 7. The song, which was one of the biggest hits of that year, was released as a single off his fourth album "Motion" that came out in November 2014 and featured another collaboration with Goulding called "Outside" and the James Newman-assisted "Blame".

The DJ returned with new music in July 2015, when he dropped "How Deep Is Your Love" which was his collaborative project with London-based production trio Disciples. In April 2016, he announced that he'd reunited with Rihanna for a new song called "This Is What You Came for". The track became Harris and RiRi's next big hit. It has so far peaked at No. 6 on Billboard Hot 100.
