Sami started his musical experiences sometime around 1996, with computer software called trackers. Joni has always been keen to different kinds of music. As he hasn't been producing as much as Sami, he has a sheer talent in writing lyrics. Valve was born in September 2006, when Sami had almost finished his new track, that didn't quite fit to be released under his other guises.
