They join the likes of Autechre, Iggy Pop, The Jesus & Mary Chain, Pavement, and FKA twigs on the bill, who were confirmed to be playing next year's event last month.

This year's edition of the festival was due to take place last weekend but was postponed to 2021 due to the COVID-19 pandemic. Many of next year's confirmed acts were due to play this year's edition.
