Stuart Langelaan, stage name Lange, (born 4 June 1974) is a British DJ and record producer.
Lange's career began in 1997, signing his first recording contract with Additive Records in the UK. Early popularity was achieved with a collection of releases attracting the attention of industry leaders such as Paul van Dyk, Sasha, Paul Oakenfold and Judge Jules.
A mixture of slow build ups and melodic choruses gave Lange several hits in the UK Singles Chart. His first success was his remix of DJ Sakin's "Protect Your Mind", which became a club track. This was followed by his Lost Witness "Happiness Happening" remix. Other remix credits include work for Faithless and The Pet Shop Boys (the Lange remix of "New York City Boy" featured on their PopArt album's bonus "remix disc").
"Drifting Away" reached #9 in the UK Singles Chart in 2002, and resulted in Lange performing on the BBC One's Top of the Pops and also the Pepsi Chart Show. Lange was also behind the SuReaL track "You Take My Breath Away", which peaked at #15 in the UK in 2000.
Lange mixes have accumulated many appearances on compilation albums, including two tracks on the million selling EMI Now That's What I Call Music! series. Other more club-orientated projects include his 'Firewall', 'LNG', and 'Vercetti' guises. In 2003, Firewall's "Sincere" was released on Armin Van Buuren's A State of Trance record label, and was re-released on Lange's own label, Lange Recordings.
Lange has found similar success as a club DJ, reaching #37 in the DJ Mag poll. As well as playing some of the UK's biggest clubs (including Godskitchen, Gatecrasher, Passion, Gallery, and Slinky), Lange regularly tours internationally. Touring has taken him to Australia, Denmark, Finland, Germany, Hungary, Japan, Netherlands, New Zealand, Russia, China, Singapore, Sweden, Switzerland, Ibiza, Canada and the United States. Lange has headlined music festivals including Australia's Summadayze (alongside Tiësto), the Popsicle festival in San Francisco, Spooky and WEMF in Canada, and Fortdance in St Petersberg performing alongside Ferry Corsten and Tiësto.
He released his debut album Better Late Than Never on Maelstrom and Lange Recordings in 2007. The album had one CD of new material, and a second disc called 'History' that highlighted some of his past hits from 1998 to the present. Three singles from the album had successful releases, these were "Songless", "Angel Falls" and the most successful release was "Lange feat. Sarah Howells - Out of the Sky". This release retained a top 10 position on the Beatport Trance Chart for a considerable time after the tracks release in October 2008, and earned Lange the nomination as one of the Beatport Top 10 selling Trance Artists in 2008.
In 2010, he released his second album, Harmonic Motion.
