How 'Embryo' Went from a 1968 Jam to a 1970 Studio Piece – and Why It Never Made a Real Album

‘Embryo’ started life as a loose improvisation during Pink Floyd’s 1968 BBC sessions, a sketch of eerie organ and wordless vocals meant to fill time. By 1970, the band had turned it into a full studio recording for the compilation Picnic – A Breath of Fresh Air, a sampler put out by their label Harvest. That version is haunting, with David Gilmour’s chorused slide guitar, Rick Wright’s droning keys, and a rare, clear vocal from Gilmour singing Syd Barrett–esque nursery-rhyme lyrics: “You sowed the seed / And you sowed the seed.” It sounds like a bridge between A Saucerful of Secrets and Atom Heart Mother.

So why did it never appear on a proper Pink Floyd album? The band simply grew beyond it. By the time they had a chance to re-record or slot it onto a record, their sound had moved into orchestral territory (Atom Heart Mother), then into pastoral precision (Meddle). ‘Embryo’ was a transitional piece, too fragmentary for a studio album and too associated with the live improvisation of 1968–69. They performed it onstage for a few years (check out the Ummagumma live half, wait, no – it wasn’t on that album, but a 1970 BBC version exists), then dropped it entirely after 1971. The song has never been officially reissued on CD, making its Picnic appearance the only official release – a ghost track from a band still figuring itself out.
