Karri Koira rose to fame as a member of the group Vähäiset äänet and gained even wider audience in the summer of 2011 with Ruudolf on the single "Mammat riivaa", a Finnish remake of "Danza Kuduro" by Lucenzo and Don Omar.

Karri Koira has stated that he draws inspiration from artists such as Ginuwine and D'Angelo.

[3] Karri Koira's first solo album K.O.I.R.A., produced by Ruudolf, was released on 30 November 2012.

[5] While the album leans more towards R&B than rap, Karri Koira has said that it is all part of natural evolving, not a chosen decision.

[7] Four singles with accompanying music videos have been released from the album; "Amerikankotka liitää" featuring an appearance by Ruudolf, "Kaikki tai ei mitään", "H-Kaupunki" and "Lähe mun kaa".
