Parkway Drive and Nothing But Thieves are among the latest addition to this year’s Reading and Leeds festivals.
They join previously-announced bill-toppers the Red Hot Chili Peppers on the weekend of August 26-28 at the twin events.
Eagles of Death Metal, Twenty One Pilots, Slaves and Crossfaith were already on the bill.
Organiser Melvin Benn said in December: “It’s going to be our best year yet.”
Tickets are on sale now for both Reading and Leeds.
