Hidden Details is the eleventh studio album by the jazz rock band Soft Machine, released in September 2018.

Hidden Details is the first album released under the Soft Machine moniker since Land of Cockayne in 1981, with a six-night residency at Ronnie Scott's club in 1984 being the last time Soft Machine were active until 2015.

From the 1984 line-up were drummer John Marshall, who joined Soft Machine in 1972, and guitarist John Etheridge, who joined in 1975 and left in 1978 before re-joining for the 1984 shows.

Bassist Roy Babbington, who was with Soft Machine during 1973 to 1976, was also included, while Theo Travis completed the line-up on keyboards and saxophone.

"The Man Who Waved at Trains" is a rerecording of a track written by original member Ratledge from their 8th album Bundles.
