This year’s 107.7 The End’s Deck the Hall Ball is a veritable who’s-who of alt-rock all-stars and up-and-comers. England’s Royal Blood, which toured with the Pixies earlier this year, will open, followed by Australia’s Vance Joy, who recorded his debut album, Dream Your Life Away, at Woodinville’s Bear Creek Studio. South African quartet KONGOS follows, then TV on the Radio will play songs from its latest, Seeds, before Mind over Matter rockers Young the Giant perform. Cage the Elephant is next, followed by Weezer, the enduring geek-rock group that recently released Everything Will Be Alright in the End. Imagine Dragons, whose 2012 song “Radioactive” is still ruling the airwaves, will close. KeyArena. 3 p.m. $50 and up. All ages.
