[3] Inspired by a Halifax Oxford Theatre midnight screening of The Wizard of Oz's audio swapped with Pink Floyd's The Dark Side of the Rainbow phenomenon, Aucoin recorded an EP, claiming it syncs with the Dr. Seuss’ 1966 film How the Grinch Stole Christmas!.

[7] Aucoin's first show was on December 20, 2006, at Tribeca in Halifax and released Personal Publication EP in 2007/2008 managed by mixing record producer Joel Waddell.

[13] Associated acts of Aucoin include fellow Canadian band members that have collaborated at venues and recording studios include;[14][9][3][15] Break Glass with Jace Lasek, Hotel 2 Tango with Howard Bilerman, Common Ground with Andrew Watt, Echo Chamber with David Ewenson, Halla with Paul Aucoin and at St. Mary's Basilica Cathedral with Peter Togni and a session at the famed Abbey Road Studios in London, U.K. featuring on Doug Taylor's album,[6] mixed by David Wrench and mastered by Nilesh Patel at The Exchange and produced by Joel Waddell.

[20][21] Aucoin decided to go back to syncing the album with just one piece of media rather than the collage of public domain films for We're All Dying to Live and so Ephemeral plays as an alt soundtrack to the 1979 Will Vinton claymation movie The Little Prince.

[22][23] Aucoin recorded an audience of 20,000 of festival performances in the summer of 2012 all over Canada, US and Europe shows for Ephemeral's opening track, Meaning in Life.

[3] Recording took place at Hotel 2 Tango with Howard Bilerman, Rooster studios with Don Kerr, Echo Lake with Daniel Ledwell, Dream House with Alex Bonenfant, and St. Mary's Cathedral Basilica in Halifax, with Peter Togni.

[28][3] Aucoin was privileged to perform his album song with Symphony Nova Scotia in collaboration with The Halifax Pop Explosion.

[7][31][32][33] featuring around 70 performers such as drummer Justin Peroff of Broken Social Scene as well as Tony Dallas of Fake Shark and Bratboy and Jeremy Malvin of Chrome Sparks, vocals of Rose Cousins and Reeny Smith, acoustic guitar of Dan Mangan and the bass of Commander Meouch of TWRP.

Taurus Recording with Thomas D'arcy, The Nook with David Plowman, Sonology with Jeff McMurrich, Planet Studios with Jean-Bruno Pinard, Hotel 2 Tango with Howard Bilerman, Virtue and Vice with Ben Talmi, Echo Lake with Daniel Ledwell, Old Confidence Lodge with Diego Medina, Alley Road with Lukas Pearse, Sonic Temple with Darren Van Niekerk, New Scotland Yard with Thomas Stajcer and again with Peter Togni recording church organ at Cathedral Church of All Saints and was produced by Aucoin and Joel Waddell and was mixed by Howie Beck and mastered by Noah Mintz.

[41] Unlike previous albums, this was unintended to be synced to a film, instead entirely based on emotional reception of the American landscape and society.

[45] Aucoin released a stand-alone single in 2022 called We're in It Together which featured a choir made up of 100 fans emailing their voice memos and home recordings to Aucoin and featured: Doctor Sung and Lord Phobos of TWRP, Ninja Brian of Ninja Sex Party and Dylan Germick of Planet Booty.

[46][47] Aucoin started Synthetic: A Synth Odyssey LP in March 2020 while doing an Artist In Residency at the National Music Centre in Calgary, Alberta.

[50] The album featured the legendary Tonto synthesizer made famous by Brian De Palma in his film Phantom of the Paradise and used by greatest like Stevie Wonder.

[52] According to The Globe and Mail, "Aucoin's sweat-soaked shows are near legendary events of mosh-pit euphoria, surfboard situations and dancing underneath a multicoloured parachute".

Often times, the framing of a night at the movies is used with opening previews of the other bands on the bill to fake advertisements and a crowd singalong of all the major media companies’ fanfares mashed up together.

[60][61] Some configurations are drums, bass, synths, guitar, horns and back up singers to having larger bands with strings and choral groups.

[47] He opened festival stages for M83, Andrew W.K., Of Monsters and Men, The National, Mavis Staples, The Flaming Lips and The Tragically Hip.

[66] Aucoin has supported Dan Deacon, Girl Talk, Deerhoof, of Montreal, Caribou, Holy Fuck, The Constantines, The Weakerthans, July Talk, Zeus, Mac DeMarco, Plants & Animals, Rubblebucket, Peelander-Z, Austra, Tegan and Sara, A Tribe Called Red, Mother Mother, Shad, Sloan, Joel Plaskett, St. Paul & The Broken Bones, Izïa and Melissa Auf der Maur.
