The Indigo started in early 2003, when university roommates L. Päivärinta and J. Siekkinen had discovered having a similar taste for music and the skill of writing great songs. These two then gathered a line-up of five musicians to form a group later named as The Indigo. The line-up proved to be working well from the very start.

During their first years, The Indigo gigged with an accelerating pace in Finland. By 2006, The Indigo had produced three demo-cds. In the making of those early demos, the band learned many valuable lessons and the vision of how The Indigo should sound on a recording started to evolve.

The Indigo's two singles 'Killing Time' (September 2006) and 'Zodiac Skylight' (May 2007), were proud representatives of The Indigo's ever improving sound. In essence, they both carried the live spirit of The Indigo while the recorded sound of the band was still moving towards more layered and broader form. Both singles received excellent feedback from the listeners and music critics alike. Both singles were also welcomed in Finnish radios, and Zodiac Skylight went on to win the coveted prize of 'Best Song By Unsigned Band' of the biggest Finnish radio channel YleX in July 2007.

In April 2008, The Indigo released their debut EP, the 'Wait'. It was released through the band's own record label, Willowcape. The EP's five tracks received a warm welcome from media representatives and, most importantly, the listeners. Several of the EP's songs were aired on Finnish radios and the many music critics stated that with this release The Indigo claimed its place among the very top of Finnish poprock. The Indigo's second EP, 'Tideturning' (October 2009), introduced three new songs and some new approaches in the production. For most part the music on the 'Tideturning' -EP was recorded in live takes of whole band. Preserving this organic warmth was one of the production team's most important guidelines while polishing the EP's sound.

In January 2010, The Indigo entered Sonic Factory -studios to record their debut-album, 'All The Secrets'. A single from the album, 'Make Believe', was released November 2nd 2010, and the release date for the album is set on 11th of February, 2011.
