He played in several well known bands since mid-1970s, most notably Tabula Rasa, Catwalk and Q.Stone. He also released several solo albums.
Ironically, Silvennoinen did not gain nationwide fame until early 1990s when he started to act and write sketches to Kummeli, a massively popular TV sketch show in Finland.
He was married to Toni Lähteenmäki.
