San Diego's Thousand Below craft emotionally heavy post-hardcore that spans from crushing metalcore anthems to atmospheric rock and heartfelt ballads, anchored by vocalist James Deberg's ability to channel raw vulnerability into cathartic musical moments. Formed in 2016 after Deberg's departure from Outlands, the band quickly earned a deal with Rise Records and built a devoted following with albums that wear their heart on their sleeve. Their fourth studio album 'Buried In Jade' demonstrates the continued evolution of a band that refuses to be confined to a single sonic identity.

Orange County's Thrice have spent over two decades evolving from post-hardcore firebrands into one of rock's most artistically restless and respected bands, with each album representing a deliberate stylistic leap. From the hardcore fury of 'The Illusion of Safety' through the experimental four-element concept of 'The Alchemy Index' to the atmospheric beauty of 'Horizons/East,' Dustin Kensrue's thoughtful lyricism and the band's chameleonic musicianship have attracted a fiercely devoted following. Thrice's refusal to repeat themselves, combined with their consistent live excellence, has earned them a legacy as one of post-hardcore's most important and enduring acts.
