Born in Saarbrucken Germany and raised in Owen Sound Ontario, Sebastian Ostertag began learning the cello at age six and has become known for his passion and dedication for all musical styles of music from Haydn to Hip-Hop.
An engaging soloist, Sebastian has performed with the Georgian Bay Symphony, the Kincardine Summer Music Festival Orchestra, as well as on CBC Radio and Classical 96.3 FM.
