In 2005, the One O'clock Marimba band was established as a vibrant addition to the music department and they performed at various functions during the year. Certain Southern African schools and institutions have been using marimbas since the 1970's, although their popularity in mainstream schools has only recently become apparent. Marimbas provide a unique medium for allowing learners to create music without the benefit of formal musical training.
In 2006 and 2007 the group's popularity increased resulting in invitations to perform at weddings, corporate events and concerts. The group consists of 4 marimba players and 1 percussion player on the congas and bongos. The group focuses on the African and Pop genres and this creates a unique vibe on these African instruments.
