About IOS
IOS, the Groningen band that got their start under the name IsOokSchitterend, hit the ground running in 1997 when their debut single Voltooid Verleden Tijd spent thirty weeks in the Dutch Top 40. It came from their debut album Hemel & Aarde, and signalled the beginning of roughly fifteen years at the top of Nederpop.
