The Indigo was formed by five musicians living in Jyväskylä, Finland. Former roommates Päivärinta and 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.

Since 2003, The Indigo has gigged with an accelerating pace in Finland. During the band's first three years, The Indigo 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 evolving 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 Records. The EP's five tracks received a warm welcome from media representatives and, most importantly, the listeners. Several of the EP's songs have 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 latest release, Tideturning (EP, October 2009) presents the band stronger than ever before. Some new approaches in the production are bringing to the front the strongest of The Indigo's elements: live playing. Most of the tracks for on all songs of the Tideturning -EP were recorded in live takes of whole band. Preserving this 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 to record their debut-album. The album's tracks were mixed in summer 2010. More information on the album's release will be made public in late September.
