You is the fifth studio album by Gong, released by Virgin Records in October 1974. It is the last album by Daevid Allen's iteration of the group until 1992's Shapeshifter. Recorded at Virgin's Manor Studios in Oxfordshire, England, side 1 was mixed at Pye Studios, Marble Arch, London, while side 2 was mixed at The Manor. It was produced by Simon Heyworth and Gong "under the universal influence of C.O.I.T., the Compagnie d'Opera Invisible de Thibet", and also engineered by Heyworth. Original Virgin LP press came with an insert, and was the last of the Virgin labels to use the coloured Roger Dean design (without copy right text), Gemini girl and lizard, without copyright text. (Some Modern issues mimic this design)

You is the third of the "Radio Gnome Invisible" trilogy of albums, following Flying Teapot and Angel's Egg. The trilogy forms a central part of the Gong mythology. The structure of the album mixes short narrative pieces with long, jazzy instrumentals (such as "Master Builder", "A Sprinkling of Clouds" and "Isle of Everywhere"), building to a climax/conclusion with "You Never Blow Yr Trip Forever".

Lead guitarist Steve Hillage remade "Master Builder" as "The Glorious Om Riff" on his 1978 album "Green".

The series of albums have inspired bands in all shapes to perform versions of the songs, even winning accolades from Rolling Stone

Japanese psych-rock band Acid Mothers Temple also frequently cover "Master Builder", entitled "Om Riff", and have released 2 full albums dedicated to album-length renditions of the song: 2005's "IAO Chant From The Cosmic Inferno" and 2012's "IAO Chant From The Melting Paraiso Underground Freak Out".

British ska band The Beat incorporated the "Master Builder" riff into live performances of "Mirror in the Bathroom" during their 2000's reunion, as can be heard on their 2013 live album "Live In London".
