RocSoc is one of the most active and popular extra-curricular societies within the School. At RocSoc boys develop their skills and experiment with creating contemporary rock music, which is of an extraordinarily high standard.

One of the first Foundation projects was to provide musical equipment for the RocSoc. including amplifiers, keyboards, speakers, a mixing desk, electronic keyboards and a drum kit.

The most prominent example of the heights to which these boys can reach is the band Coldplay, whose lead singer is a young OS.
