Since 1975 (7 years old) Theo has been working with rhythms, as drummer in a fanfare band, as percussion soloist and as percussionist in ensembles. He participated in several musical competitions. In his student days he started to play as drummer in pop / rock bands, including several bands with Roland ("Night Heat", "Daffodils in the Desert" "Into the Abyss, "Houdbaar" and "Forty Shades of White"). Especially the last band was very successful, as evidenced by a large number of performances (eg with "Krezip" and "Rosemary's Sons") and a beautiful studio CD. In recent years he became interested in other music styles (jazz, fusion, flamenco), this fueled by participating in workshops and experimenting with other musicians ("Live from the Attic").
