Riddle’s latest King Black Acid effort, Telling Secrets in a Crowded Room is slated for an August 21, 2026 release through Cavity Search Records/Mazinga Records. The album reportedly features 10 cinematic and anthemic songs that “embrace total and subversive emotional anarchy.”

Telling Secrets in a Crowded Room‘s latest single “Dialing 911” is a sleek and mind-bending synthesis of Madchester-era sound, Evil Heat-era Primal Scream and Echoes-era The Rapture dance punk that showcases the collaborators uncanny ability to craft a remarkably catchy hook.

“Fierce stoner pop that explores the fragile human psyche in the modern digital thought prison,” the band says of the new single.

KThe accompanying music video by Kat Perkins and Daniel Riddle features a mix of collage-driven animation reminiscent of The Beatles‘ Yellow Submarine and the intro to Monty Python with strobe lit, monochrome footage of Riddle and dancing and instrument playing humanoid rabbits. Trippy, indeed.
