Eric Sheridan Prydz ( /ˈprɪdz/ ; born July 19, 1976), also known by his aliases Pryda /ˈpraɪ.də/  and Cirez D , /ˈsaɪ.rɛz.diː/ is a Swedish DJ, record producer and musician residing in Los Angeles, California.
2004–08: Call on Me and Swedish House Mafia
Prydz is perhaps best known for his 2004 hit single " Call on Me ", which samples the Steve Winwood hit " Valerie ".  It topped the UK singles chart for five weeks  and was number one on the German Top 100 for six consecutive weeks.  Although this track made him immensely popular, Prydz has stopped playing it in his shows in an attempt to distance himself from it. In some respects he has succeeded, and with his newer songs, Prydz has gained recognition from both underground and mainstream fans.  In 2006, he released a remixed version of Pink Floyd's " Another Brick in the Wall, Part 2 ", titled " Proper Education  ", with a video. 
Together with Axwell, Sebastian Ingrosso and Steve Angello, Prydz formed a group of DJs that informally referred to themselves as the Swedish House Mafia.  When the group with the same name officially formed in late 2008, Prydz decided not to join his friends.  He has collaborated with Axwell under the name Axer  and with Angello as A&P Project.  
2009–13: Eric Prydz Presents Pryda
In 2009, Prydz released "Miami to Atlanta", which is when the "Pryda snare" was first used. The Pryda snare is a popular technique in house and trance music consisting of using a compressed and sustained snare sample at the end of a bar. Commonly used to mark progressions in a song structure, it has been widely sampled in the electronic dance music world, notably by producers such as Martin Garrix, Dimitri Vegas & Like Mike, and W&W. 
On 21 May 2012, Prydz released his debut artist album as a 3 disc set through Virgin Records. Disc 1 is made up of new unreleased Pryda productions, which some fans may have heard as works in progress (including Shadows, Agag, Mighty Love, Allein and the intro edit of Pjanoo). Discs 2 and 3 bring together many of the classic tracks from the Pryda catalogue, sequenced and mixed by the man himself, including some of his special re-edits. 
The Ministry of Sound club in London hosted the launch of Eric Prydz Presents Pryda on 14 April 2012, where Prydz played some of the tracks from the album.   Inserting the CD in a computer and visiting Prydz's Facebook page provides access to a download of 'Tijuana', a track previously known as 'Space Miami ID' in . WAV format. 
2014–Present: PR(10)DA EPs and Opus
2014 was the 10th year of Prydz's label Pryda Recordings, and as a result, on 9 January 2014, Prydz announced a special upcoming artist album which was initially due for release later that year.  On 4 May 2015, Prydz announced PR(10)DA, a collection of unreleased tracks from January 2004 to December 2014. PR(10)DA was released over three EPs, leading up to an album release in February 2016.
On 19 May 2014, Prydz announced via social media the third installment of his concert, Eric Prydz in Concert, titled EPIC 3.0. Promising the 'world's largest indoor hologram', new music, and new visuals, the show was to be held at Madison Square Garden during the Fall.  Prydz performed his EPIC 3.0 show on 27 September 2014, playing a large range of new and unreleased material.  The show incorporated a 20m, 4K hologram, and 32 lasers.  
On 4 July 2015, Prydz was the first DJ with a set featured as a "One Mix" on Beats 1, the worldwide radio station on Apple Music. 
On 28 June 2016, Prydz collaborated with Luke Versalko from Mashable to produce a short documentary that details the making of his Epic 4.0 show. 
Aside from producing music, Prydz also runs the record labels Pryda, Pryda Friends and Mouseville, which release most of his own music.  On Pryda, he releases music as Pryda. On Mouseville Records, started in 2002, he releases techno tracks as Cirez D.  Prydz has a fear of flying, which means he mainly tours on a bus.
