Scream Thy Last Scream: Syd Barrett’s Unhinged Vocal and the Anti-Single

Recorded during the same 1967 sessions that produced “See Emily Play,” “Scream Thy Last Scream” is Pink Floyd’s weirdest almost-single. Syd Barrett takes the lead vocal — and he doesn’t so much sing as jabber, cackle, and mutter through a fairground nightmare of backward tapes, distorted percussion, and lurching tempo shifts. Where “See Emily Play” is dream-pop tightly wound, this is a cracked music-box that keeps falling off the shelf.

Structurally, the song abandons any verse-chorus anchor. It cycles through cartoonish vocal lines, a clattering middle section with toy xylophone, and a manic spoken-word breakdown that sounds like Syd improvising in the studio after too much tea and staring. The band never released it during Barrett’s tenure — likely too chaotic for single consideration — yet it predicts the more playful psychedelic freakouts on The Piper at the Gates of Dawn’s second half. For fans, it’s the closest audio snapshot of Syd’s brain at full tilt.
