Embryo (Pink Floyd song)

"Embryo" is a song written by Roger Waters and originally performed by Pink Floyd. It was a staple of their live performances between 1968 and 1971, often extended with improvisational sections. While never officially released on a studio album by the band itself during that era, a studio version appeared on the Harvest Records compilation album Picnic – A Breath of Fresh Air in 1970.

The song's lyrics are somewhat ambiguous and open to interpretation, potentially referencing nascent life or unrealized potential. Musically, "Embryo" features a gentle, pastoral melody contrasting with moments of experimental and sometimes chaotic instrumental passages during live performances. These live improvisations showcased the band's early psychedelic style and their ability to create dynamic soundscapes.

The studio version of "Embryo" is relatively short and more focused than the extended live renditions. Its inclusion on the Picnic compilation, rather than a Pink Floyd album, has made it a sought-after track for collectors. The existence of numerous bootleg recordings further attests to the song's popularity and significance within Pink Floyd's early catalog. The song was eventually included on the band's 2016 box set, The Early Years 1965-1972.
