Welsh nine-piece collective MWSOG have released their spellbinding debut single “Chwyldro” via BWGiBWGAN, blending the ancient pulse of Cymru’s folklore with the fire of modern rebellion. Translating to “Revolution,” the track gallops forward on thunderous drums and harmonium, merging the raw beauty of Welsh storytelling with a dark, ritualistic energy. Mari Mathias leads with a voice that feels both elemental and eternal, channeling the spirits of myth and history through waves of acid-folk and heavy psychedelia. “MWSOG allows me to embody the teachings of the Mabinogi, ancient voices so old we can no longer trace their source,” she says. “Much of what we write follows these quiet threads – the weaving of nature and metal, the pulse between the industrial and the soil.”
Recorded beneath the ancient standing stones of the Preseli Hills, “Chwyldro” draws from Wales’ long tradition of uprising and endurance, from the Rebecca Riots to the echoes of miners’ songs. “We wanted to retell the struggles of our ancestors through modern musical language,” says drummer Luke Huw Llewellyn. Guitarist Grant Jones adds, “It felt ancient, like it had been waiting to be found.” Produced by Steffan Pringle, the single captures a collision of past and present – the sound of ghosts, rebellion, and renewal. MWSOG’s live performances are already building myth of their own: wild, communal, and steeped in ceremony. With “Chwyldro,” they emerge as torchbearers of Welsh culture and defiance, transforming tradition into something bold, mystical, and fiercely alive.
