Canadian singer Lights will return to the UK for the first time since 2016, to make her debut at Slam Dunk Festival.
The 31-year-old musician - who is known for her gold-certified albums 'The Listening' and 'Siberia', as well as singles 'Drive My Soul', 'February Air', 'Ice', 'Second Go', 'Toes', and 'Up We Go' - has joined the one-day event along with blasts from the past, Plain White T's and 'Here In Ur Arms' hitmakers Hellgoodbye.
Lights said "I’m so pumped to be on the Slam Dunk bill for the first time. Not only am I excited to play with a bunch of great bands, but it’s been over two years since I’ve been back in the UK so needless to say Slam Dunk can’t come soon enough.”
The latest line-up additions also include Touche Amore, Tigers Jaw, and Microwave.
Metalcore legends Atreyu will make their debut at Slam Dunk Festival in May - for what will also be their first show on UK soil since playing Download Festival in 2016.
The Alex Varkatzas-fronted band said: "It’s been far too long since Atreyu has touched down on UK soil. We can’t think of a better way to break the silence than Slam Dunk Fest! Get your big kid pants on ... it’s gonna be a ripper!”
Also joining the already-epic bill is pop punk stars Milk Teeth, WSTR, Real Friends, Seaway, Pagan and The World Alive.
Meanwhile, The Bronx, Cancer Bats and hardcore supergroup Angel Du$t - comprised of members of Trapped Under Ice and Turnstile - have been announced to join Glassjaw, Gallows, Turnstile and Knocked Loose on the Impericon stage, with another heavy stage also set to feature at the festival.
All Time Low are set to headline at the one-dayer, which takes place at Temple Newsam Park in Leeds on May 25 and Hatfield Park on May 26.
