Trainwreck is the second studio album by Canadian rock band Boys Night Out, released on July 26, 2005 through Ferret Music.

Trainwreck is a concept album about a character known as The Patient murdering his wife, being hospitalized and trying to convey the music he hears in his head.

[3] Fordirelifesake drummer Brian Southall filled Arseneau's role from mid-2004, and vocalist and guitarist Jeff Davis took up both lead and rhythm parts in the aftermath of Pasalic's departure by the end of the year.

While in the writing process, they became aware that they needed a strong female voice, at which point Southall drafted in keyboardist Kara Dupuy.

[3] They were hesitant about making a concept album, as Davis explained that some people associate the phrase with The Dark Side of the Moon (1973) by Pink Floyd, and "[i]t's a very pretentious-sounding thing, and we wanted to avoid that".

[3] Davis, Southall, Machine, Sam Hinzes, Dupuy and Diane Pacenka contributed group vocals, which were recorded at Harariville in Weehawken and engineered by Rob Harari.

[5] The Patient's frustration is fuelled by the self-inflicted loss of his hands, which Davis said related to the band "wanting to do something, but having never really written any form of real music before, and never being happy with anything we've done".

[3] Dupuy plays the deceased wife, "whose ghostly wail methodically crawls up all vertebrae as the most grisly case details are uncovered", according to Seabaugh.

[11] Shultz said in "Introducing", a character called The Doctor is "recording notes about The Patient following one of a few hospital releases granted to him".

[12] From "Dreaming" onwards, The Patient serves in the lead role, as the listener "follow[s] his attempts at recreating the aforementioned song", according to Shultz.

[8] "Medicating", which recalls the work of Sunny Day Real Estate, sees The Patient attempting to convince The Doctor that he is mentally stable for hospital release.

[8][12] Shultz said "Purging" features the majority of the "remaining screaming left in the band's system; if they're trying to convey The Patient's actual state of mind".

Dupuy's part as the wife appears in the Bright Eyes and Denali-indebted "Relapsing", where The Patient thinks he can hear her voice in his head.

[8] Peter Gaston of Spin referred to the song as a "Warped Tour-ready version of Fleetwood Mac" due to the vocal interplay between the pair.

[13][14] On May 29, 2005, the album's artwork and track listing was posted online; alongside this, "Composing" was made available for free download through the band's Myspace profile.

[13] Design company Switzerland did the layout for the album and Gordon Ball took the photography, which showcases The Patient at different points of the story.

The staff at AllMusic wrote that Lovat-Fraser was "still prone to abrupt bursts of shouting, most of his vocals are melodic and energetic, reflecting the guitar-heavy (and sometimes complex) tunes on offer".

[9] Melodic writer Kaj Roth said it sounded "top notch, but the music is what makes this so interesting - you will find new things every time you listen to this record".

He said compared to other acts doing concept releases, Boys Night Out were "mostly to the point, simple enough lyrically to clue the listener as to what's going on while at least keeping some open interpretation to it".

[11] Scott Hefflon of Lollipop Magazine dismissed the album, stating: "They may like Muse and The Mars Volta, but they sound like Fall Out Boy".
