Timo Tolkki
In November 2010, Matos joined Symfonia, a power metal supergroup formed in with Timo Tolkki, Uli Kusch, Jari Kainulainen, and Mikko Härkin. They made their debut performance at Finnish Metal Expo 2011 and released their first and only album "In Paradisum". As touring and second album plans didn't work as planned, Timo Tolkki (guitarist, ex-Stratovarius) announced that he would stop his life in the music industry and that Symfonia would not continue as a band.
