ARCTANGENT Festival 2026 Announces First Line-Up Featuring Igorrr, Alcest, Perturbator, and More
The UK’s most beloved celebration of math rock, post-rock, and all things experimental, Arctangent Festival, returns to Fernhill Farm from 19th–22nd August 2026, and the first wave of acts has officially dropped.
Topping the announcement isa UK exclusive from Igorrr, the mind-bending French artist and producer Gautier Serre’s project.
Joining Igorrr are Alcest (UK exclusive), and Perturbator (UK exclusive), Chat Pile, Oathbreaker (UK exclusive), returning to the UK for their first show in years; and the return of Iceland’s Agent Fresco, who will play their first shows in seven years. British math rock heroes TTNG are also back after a seven-year hiatus.
Adding to the nostalgia and chaos, HECK will reform to celebrate the 10th anniversary of their cult classic album Instructions, while post-metal outfit Humanfly will play their first show in 13 years. Other names joining the lineup include Town Portal, Shearling, and Michael Cera Palin.
The Wednesday lineup has also been partially revealed, featuring Svalbard who will play their final ever festival set alongside Lost In Kiev, Alpha Male Tea Party and more.
Amplifier will return with a special live Silent Disco set.
Festival organiser James Scarlett shared his excitement, saying: “The demand for ArcTanGent 2026 tickets has truly been unprecedented, with over half our tickets sold in the first 2 weeks of them being on sale. Fans will have to wait a little bit longer before we can announce our headliners, but we’re so excited for the exclusives, reformations and special sets we’ve already cooked up. Early Bird tickets are running low, so if you want to lock in for another vintage ArcTanGent, don’t sleep!”
ArcTanGent 2026 is shaping up to be one of the festival’s most memorable editions yet.
