NIRVANA, The Who, Green Day and Muse are not the first acts that come to mind when you think about choirs.

But Os Rocks specialises in reworking music by a host of rock and pop acts and transforming it into impressive choral arrangements – all while promoting the benefits of singing for wellbeing.

Founder Jan Ellis – a keen attendee of choral competitions in her native Huddersfield – established Os Rocks in March 2017 after noticing a lack of choirs singing pop and rock tunes.
