Timo Aulis Rautiainen (born 25 January 1963, in Sulkava, Finland)[1] is a Finnish heavy metal singer, guitarist and songwriter.

In the early stages of Trio Niskalaukaus, Rautiainen was commonly represented in the main media as "The Grim Teacher", because of his strong and rather gloomy lyrics and his occupation.

Despite his earlier and solemn representation in Finnish media, he is actually a man with a good sense of humour, and he is characterized by his laid back nature on stage.

The album featured the talents of Nightwish founder Tuomas Holopainen (who also wrote one song) and former Children of Bodom guitarist, Alexander Kuoppala.

The line-up changed a bit, and Jarkko Petosalmi, former Trio Niskalaukaus guitarist, joined Rautiainen's solo band.
