Ghislain Poirier

In January 2010, Poirier's music was used alongside Flying Lotus and Roberto Carlos Lange, among others, as the soundtrack to New York artist Brian Alfred's It’s Already the End of the World, "a solo exhibition of new work by Brooklyn artist Brian Alfred...featur[ing] 14 new paintings, collage works, and a major new video work". In March, Poirier released Running High, an album that brought together tracks from the previous three EPs as well as additional new material and remixes by "Wildlife!, Mungo, Uproot, Marflix, Maga Bo, Stereotyp, and Poirier himself".

In 2009 Poirier began the release of three EPs to be completed over the course of a full year, the first of which was Soca Sound System (April 2009) which included guest appearances by MC Zulu as well as soca performer Mr. Slaughter. Where Soca Sound System experimented with soca, the second Run The Riddim experimented with dancehall and the third, Low Ceiling, which came out in early 2010, focused on dance music with no vocals, "said to be inspired in part by his early years in the underground rave scene" Run The Riddim was the first release under the shortened name Poirier. All of the three EPs featured cover art by Montreal-based photographer Guillaume Simoneau.

Also in 2009, he was featured on a Truckback Records remix project for dancehall artist Erup's hit "Click My Finger" alongside Grahmzilla of Thunderheist, Nick Catchdubs and Lunice.

Poirier's first Ninja Tune full-length release was 2007's No Ground Under. Though rappers Omnikrom appear on the album, the record deviated from his previous work, focusing instead on dancehall, including vocalists Face-T and MC Zulu. In 2008, he was invited to perform at the New Yorker Festival.

Poirier is well known in Montreal for a series of successful club nights entitled Bounce Le Gros (roughly translated as "Bounce Dude"). At these events Poirier experimented with "grime, crunk, hip-hop, ragga, reggae, booty house, Baltimore breaks...original urban music from all over the world". Bounce Le Gros began in 2005 at small local club Zoobizarre and then moved to larger venues as Poirier experienced increasing success. The last edition was held in the summer of 2007. During the same summer, Poirier, alongside Megasoid and DJ Khiasma held a large illegal outdoor party on St-Jean Baptiste Day, 24 June. The party was so well received that it recurred in August 2008 and again, alongside Pop Montreal on St-Jean Baptiste in 2009. As Megasoid's Speakerbruiser Rob describes: "Bridge Burner has really become an amazing event, mostly because it has received support from a good diverse group of people...with great promoters getting on deck, Pop Montreal, RedBull, Mike D, Khiasma, Ghislain and a lot of heavyweight local volunteers. [2009] was the biggest, and most visible, and most successful, but truthfully, the first one will always hold the space in my heart." In October 2009, Poirier introduced a new event called Karnival. Paul Devro (Mad Decent), Dub Boy (Ruffneck Diskotek, Bristol) and Face-T were featured. The second edition was held in February 2010 and included performances by Bonjay, Ghostbeard, Boogat and Face-T as performers and was filmed for a video for the new single "Arena" by Crookers featuring Poirier and Face-T.

From 1995 until 2000, Poirier was involved in campus community radio at CISM-FM (Université de Montréal). During this time he had a radio show entitled "Branché: Monde". He began his career performing and recording under his full name with his debut album, Il N'y A Pas de Sud being released in 2001. It has been described as "an uncompromising minimal electronics record that fit part and parcel with the laptop zeitgeist". Along with Deadbeat, Tim Hecker and Mitchell Akiyama, Poirier was part of "what became known as the Montreal minimal techno movement". Sous le manguier features cover art by Poirier himself.
