" data-original-title="" title="">Tomos Williams has something extra-musical to say. The Welsh language project name—Cwmwl Tystion means 'witness'—and the English title— Riot!—writ large, expel any doubt. Inspired by events both famous and infamous in Welsh history—workers revolts, pogroms and race riots—this sprawling one-hour suite is a musical manifesto for a more balanced perspective on Welsh identity/nationalism.

It is a subject close to Williams' heart. Witness (T? Cerdd, 2019)—the first installment of a trilogy—was a celebration of the Welsh landscape, language, people and culture, but also raised questions of what modern Welsh identity means. Riot! may draw on similar raw material, that is to say Welsh poetry, folk music and hymns, but it differs fundamentally in the more blood-drenched episodes the music addresses.

Alongside still-celebrated workers' revolts against low wages and poor social conditions acknowledged in "Merthyr Rising 1831" and "Tonypandy Riots 1910," Williams juxtaposes "Tredegar Riots 1911," in which the town's Jewish businesses were targeted by rampaging mobs. No less unsettling, "Cardiff Race Riots 1919" recalls white vigilante attacks on African and Asian immigrants. "Mahmood Mattan," remembers a Somali man, hanged in Cardiff in 1952, for a murder he did not commit.

The recording and commemoration of such events still ignites debate in Wales. To these episodes and their cultural legacy Williams holds a mirror, inviting reflection. He understands that Wales, like every other nation, has reasons to be proud, and equally, cause for regret. Nationalism is almost always a complex business.

So, that is the back story, what then of the music? The sprawling jazz suite was recorded over three nights on a 2021 tour of Wales, with a band featuring drummer Mark O'Connor and bassist
