Swedish producer Donnie Castle unveils hallucinogenic debut single "Oooh"

The cut's a vivid sliver of pop brilliance, with flickering xx-y guitars and big, bold melodies jammed into the bliss. It's gorgeously blurry, with dream-addled refrains and mysterious 'ooh-ooh-oohs' peering from behind a smoky facade.

"In 2015 I went through a rough breakup; we had been together for a long time. She moved to Malmö and I remained in my hometown Gothenburg. Since our intense relationship I had distanced myself from former friends and was now all alone," Castle says of the track. "This sent me down a path of pure destructiveness. During the day I earned pennies on posting bills for Gothenburg's nightlife and nights I spent in underground clubs and found a new relationship with the drug LSD. I lived fast as the light, the money i earned was never important to me. It was the contacts, the crowd and the escape from reality."
