Career
He joined the band just before they recorded the Theater of Salvation album in 1998. Fellow band members (and some fans) refer to him as "Alien Drum Bunny," referenced in the song "Save Us Now" from the album Mandrake. This is also the reason that his drum solo on the live album Burning Down the Opera is called the "Solitary Bunny Drum Solo."
He is also the live drummer for Avantasia and recorded some tracks on the 2010 albums The Wicked Symphony and Angel of Babylon.
In 2015, Felix was invited to be the drummer of melodic rock project Khymera, led by bassist/vocalist/producer Dennis Ward (Pink Cream 69, Unisonic).
He recorded drums for their last album called The Grand Design. Felix was also announced as the drummer, recording all tracks, on Avantasia"s 2016 album Ghostlights.
