Morén was studying film science in Stockholm when he met John Eriksson at a party. The following year they started a band and simply called it Peter, Bjorn & John, not due to lack of better names, but because it felt the right thing to do, as band names are often ridiculous, so why not just go for your own names? First they thought that they would recruit a bass player but after the well known saying, '...3 is a crowd ', decided they had more than enough, so keyboard player Björn began playing bass. Live the band have learned to use the smaller format to its advantage and in the studio, overdubs were the way to go.
During this period, Morén had also joined The Plan, playing bass on their 2001 self-titled debut album. However, in 2002 he decided to leave the group to concentrate on Peter Bjorn and John's first record.
Initially any fan/press attention they got had to do more with Björn's past production CV, as well as the other members guest appearances on other more well known bands records.
This began to change when in 2002 the home recorded self-titled debut album was released and songs like "Matchmaker" and "People They Know" became favourites with the indie-rock crowd.
2004 saw the follow-up with the more complete, mature and darker "Falling Out". The track "It Beats Me Everytime" became a hit on Swedish radio and the album was released Stateside the following year.
Their sound on here could be described differently to fellow Swedish bands The Concretes (who were more punk) or Shout Out Louds (who were more frantic), and certainly as catchy as the most tuneful of the UK post-post-post-punk merchants. "Falling Out" established Peter, Bjorn & John as a group to watch out for.
In 2006 they embarked on the second phase of their careers. The new album "Writer's Block" (recorded in Björn's studio in Hornstull, Stockholm) is the first to showcase all three members as songwriters with each taking on lead vocalist duties, and sees the band go into a new musical direction. The first single from the album, "Young Folks", features the vocal talents of Victoria Bergsman from The Concretes and has been hammered even before it's official release.
In 2008 the band released their first instrumental album, "Seaside Rock", with great success. The following year they released the album "Living Thing" (and a deluxe edition CD, where Seaside Rock came as a bonus CD)
DJ Mick Boogie remixed the tracks and released them in digital format, calling them "Re-Living Thing".
The biggest highlight after "Writer's Block" was the 2011 album "Gimme Some", the hit "Second Chance" became even better known as the opening theme of the American television sitcom
2 Broke Girls.
Through the years each of the band members have developed side projects where they could explore their personal tastes and styles. Peter Morén, Björn Yttling and John Eriksson reunited with other independent artists like Lykke Li, Miike Snow and some others and, on April 20, 2012 they founded the independent label INGRD.
In 2016/17 the band was touring their seventh album, "Breakin' Point"!
