Welsh collective MWSOG unveil their debut single “Chwyldro”, out now on BWGiBWGAN, binding ancient Cymru to a modern, ritual-charged pulse. Rooted in acid folk, mystical trad, and heavy rock weight, the song opens with a galloping, spell-like rhythm as drums, harmonium, and harmonised voices rise together. The response to the track highlights its fearless atmosphere, where folk storytelling meets darker power and communal intensity.
Fronted by the elemental voice of Mari Mathias, “Chwyldro” channels Welsh myth and resistance through sound. “MWSOG allows me to embody the teachings of the Mabinogi, ancient voices so old we can no longer trace their source,” Mathias says. “Much of what we write follows these quiet threads – the weaving of nature and metal, the pulse between the industrial and the soil.” The song draws directly on the Rebecca Riots, transforming historical rebellion into rhythm, movement, and ritual.
Drummer Luke Huw Llewellyn explains, “We wanted to retell the struggles of our ancestors through modern musical language,” while guitarist Grant Jones recalls the riff arriving fully formed, “like it had been waiting to be found.” Recorded beneath the standing stones of the Preseli Hills and shaped by producer Steffan Pringle, “Chwyldro” arrives as an awakening rather than a debut, carrying Welsh culture, myth, and defiance forward with fire still burning.
