THIS is the three-and-a-half minute rock song it's hoped will soundtrack a political revolution.

Welsh musician Geraint Rhys wrote and recorded Who Are You? at his Swansea home as a "wake-up call to the people of Wales" and a challenge to Boris Johnson's UK Government.

Rhys read for a Masters degree in Nationalism Studies at Edinburgh University, during which he made links with politicians and activists in Catalonia and the Basque Country.

His track, available on Spotify, was influenced by the divergence in furlough and other Covid policies between Westminster and Cardiff, with Senedd plans to provide income support for those unable to work due to localised restrictions blocked until Chancellor Rishi Sunak opted to roll out that coverage across England and the rest of the UK.

Rhys previewed a snippet of the track in the Sunday National last week.

Today he's released it in full with a video featuring scenes recorded during landmark Welsh independence marches in 2019.

Thousands attended those events, which were organised by All Under One Banner Cymru following successive mass protests in Scotland.

Rhys hopes the track will become the sound of the Welsh independence movement.

Its release comes just weeks before the May 6 elections.

Labour is aiming for control of the Senedd again and while it is against a referendom on the constitution, some of its candidates have expressed support for change.

Meanwhile, Plaid Cymru has pledged to stage a ballot if it wins a majority, despite the presence of anti-devolution sentiments amongst some Conservative candidates.

Rhys, 32, said: "This track is about feeling completely and utterly despondent and in despair at those who allegedly represent you. It is also a song bred from the centuries of neglect I feel we have experienced here in Wales.

"It’s a song about saying enough is enough and is not only aimed at those in power, but is also a rallying cry to the people of Wales to question who they want to be.

"Do we want to carry on along the same path or take a different future for ourselves?"

Yes Cymru founder and chair Siôn Jobbins, an expert on Welsh music, said: "Wales is the 'land of song'.

"There’s a strong tradition of protest songs and songs about Welsh independence or the language, especially in Welsh, since the 1960s.

"A big component of the campaign for independence is to strengthen and promote Welsh language and culture, and also culture in English from Wales.

"People writing songs, composing poetry, painting, writing plays and drama as all an important part of the independence campaign. We welcome all new songs."
