Music is the festival's core medium. Stephens' eclectic musical taste is reflected in the diversity of the artists performing, and Welsh language bands are well represented on the line-up.
Sŵn festival 2013 took place in October in Cardiff City Centre with new venues added including the Sherman Theatre & the Angel Hotel.[citation needed] This edition of the event won the "Best Small Festival" accolade at the NME awards in 2014.[3] The 2015 edition of Sŵn Festival was also nominated for "Best Small Festival" at the NME Awards.
In 2018 it was announced that Clwb Ifor Bach would take over the running of the festival as Stephens and Rostron departed.
