Ronker – The downstairs room of CLWB won’t know what hit it with our second stage headliners from Belgium. Off the back of a superb second album release they brought their high energy live show to ATG recently and blew the ruddy doors off. Be prepared for chaos. FFO: Knives, Coilguns, Metz

De’Lour – Headlining our FUEL stage we welcome De’Lour. Hailing from South Wales they will be very much representing Cardiff with their atmospheric, soaring yet heavy metal. Expect emotion and riffs galore. FFO: Periphery, Deftones, Bullet For My Valentine

Beyond Extinction – The nastiest thing to emerge from Essex since TOWIE, Beyond Extinction bring the sludgy beatdown and guttural, bowels of hell vocals and will have their new EP Three Swords in tow. Get your dancing shoes on for their appearance on our main stage. FFO The Acacia Strain, Black Tongue, Humanity’s Last Breath

Dye – Channeling late 90s/early 00s, Bristolians Dye bring their gritty grunge laden metal to Womaby street with explosive delivery. Gathering momentum recently this talented gang are definitely one to follow. FFO: Alice In Chains, Mannequin Death Squad, Lambrini Girls

Breichiau Hir – Dragging the Welsh language into the modern alternative world, Cardiff post-hardcore six-piece Breichiau Hir deliver hefty alt rock riffs with a retro Cool Cymru swagger and a DIY punk ethos. FFO: Thursday, Adwaith, Alkaline Trio

AARONSON – One of the hardest working names in the thriving Welsh post-rock scene, Aaronson bring their slow-burning atmospheres and colossal riffs back to Womanby Street. Aaronson weave sagas for anyone who likes their instrumental music immersive and cinematic. FFO: Nordic Giants, Mogwai, Explosions In The Sky

Sans Froid – Bristol based piano-led art-rockers Sans Froid have spent the last six years as one of the most unique and exciting acts in the UK’s experimental world. Bringing their disorienting and memorable sound to Noizzefest’s main stage, Sans Froid aren’t a band to miss. FFO: The Mars Volta, Peach, Geese 

An additional 11 bands will be announced in the coming months, including the Clwb Main Stage headliner. As well as partners at the festival and stage splits/times.
