Context paragraphs:
Peter Bjorn and John: Peter Bjorn and John are a Swedish indie pop/rock band, formed in Stockholm in 1999 and named after the first names of the band's members: Peter Morén (vocals, guitar and harmonica), Björn Yttling (bass guitar, keyboards and vocals) and John Eriksson, known in his solo work as Hortlax Cobra (drums, percussion and vocals).  Yttling also worked as producer for the band's first four albums.

Peter Bjorn and John (album): Peter Bjorn and John is the first album by Swedish indie-pop band Peter Bjorn and John.  Its style takes influences from baroque-pop, post-punk and soul ('From Now On'), and it is colloquially referred to by the band as 'The Red Album'.  Self-titled, it is the only album by the band not to follow their tradition of naming albums with two words, the first with two syllables and the last with one.  However, it does adhere to their rule of always having three of something, if not the band members themselves, on the front cover.  The Wichita Recordings re-release included five bonus tracks from the album's four singles; 'Firing Blanks' & 'Don't Be Skew' from the 'I Don't Know What I Want Us To Do' single, 'Le Crique' from the 'People They Know' single, and 'The Fan' and 'Saturday Night At The Parties' from the '100 M Of Hurdles' EP.  Session musicians appear on some tracks, as the band originally intended to be a quartet.  The album and its singles feature artwork designed by Eric Segol.

Scott Fitzgerald.  Morén's initial plan was to make a purely acoustic record, but the final product contains elements such as string sections and synthesisers.  It was released by V2 Records under license from Wichita Recordings.  The album was recorded "...in our spare, stolen hours, here and there in apartments, rehearsal spaces and studios in Stockholm...".  The album had two singles; Social Competence, released in March, followed by Reel Too Real in April.  The album was produced by songwriter Tobias Fröberg, and Daniel Värjö, member of The Concretes, whose former member Victoria Bergsman Morén had previously collaborated with on the Peter Bjorn And John song Young Folks.
