With its sister festival 2000trees completed with vast success, Bristol’s ArcTanGent Festival is back for another year – sporting a lineup full of the biggest names in math, prog and alt-rock. The lineup isn’t short of international heroes, bringing along Canadian post-rock instrumentalists Godspeed You! Black Emperor to close the Friday, and old Illinois heroes American Football to finish off the Saturday night.

Looking over day by day, Thursday sees the ‘returning heroes’ day – with a mixture of festival favourites taking to the stages as soon as tents are pitched down. With Bristol’s Anta starting off the festival with a bang at 2pm, names among Samoans, Rolo Tomassi, Three Trapped Tigers and Japan’s Mono follow to take the day to the fullest – ensuring a day full of action right up until 11pm.

As the first jam packed day, Friday’s music starts at 11am – with Sleep Kit, Viva BelgradoSuper Goliath and Vasudeva providing a keen wakeup call. Later in the day comes 2000trees favourites Arcane Roots and Heck, as well as American instrumentalists Animals As Leaders who graced The Cave stage at the sister festival earlier this year. Manchester’s 2-piece Cleft also make one final appearance – making their last unmissable debut as a band, before calling it a day. Bringing a bit of post-hardcore into the mix, La Dispute will also grace the mainstage alongside Japanese rockers Toe, in the build up to the 2 hour legendary headliners Godspeed You! Black Emperor.

Following strongly behind with another full 12 hours of music, Saturday’s openers Lets Talk Daggers, Skyhitch, Envoys and Bearded Youth Quest commence the final day strongly. With so many bands not to miss over the duration of the day, popular favourites Black PeaksmewithoutYou, Errors and Caspian bring significant genre diversity to the festival – from more electronic styles, to hardcore sounds and vocals. Moving towards the top of the lineup, Northern Irish legends And So I Watch You From Afar will be warming up the mainstage before the headline slot – bringing their distinctive, vibrant instrumental sounds to the well acquainted audience. With so many acts to name, the day does bow down to headliners American Football, who with only one released album from 1999 - will be one to watch with curiosity.

Alongside the acts, the site won’t be short of food catering for all dietary requirements –and even more entertainment. Both Friday and Saturday come accompanied by the famous Silent Disco after the music stops, which headphones for will be available to pick up each day for a £10 deposit. 3 day tickets aren’t sold out just yet – but snap yours up today before they’re gone – as there’s less than 800 left.
