Delicate Sound of Thunder is the first entirely live album by English progressive rock band Pink Floyd. It was recorded over five nights at the Nassau Coliseum on Long Island, New York, in August 1988 and mixed at Abbey Road Studios in September 1988. It was released on 22 November 1988, through EMI Records in the United Kingdom and Columbia Records in the United States.
The album was released in 1988 as a double LP, double cassette, and a double CD, each format containing a slightly different track listing. The album includes many works from A Momentary Lapse of Reason as well as tracks from older Pink Floyd albums. The double LP release did not have "Us and Them" on the track listing. Both the double LP and the double cassette had "Wish You Were Here" between "Another Brick in the Wall (Part 2)" and "Comfortably Numb".
Although David Gilmour stated around the time of its release and on a radio interview in 1992 that the album contained no studio overdubbing whatsoever, he embellished the tracks during mixing with some extra acoustic guitar on "Comfortably Numb", according to engineer Buford Jones. In addition, some harmonies were replaced by studio re-takes: Richard Wright re-did his vocal on "Time" and Sam Brown replaced Rachel Fury's part in "Comfortably Numb" but the rest of the album is as performed at the shows.
Along with A Collection of Great Dance Songs, Delicate Sound of Thunder was reissued on 180g heavyweight vinyl LP in November 2017. Its artwork replicates that of the original 1988 LP release.
An expanded version of the live album was included in The Later Years 1987–2019 box set in 2019, including performances omitted from the original release due to the limitations of vinyl records. Previously unreleased tracks include "Signs of Life," "One Slip," "A New Machine (Part 1)", "Terminal Frost", "A New Machine (Part 2)", and "Welcome to the Machine". This reissue marks the first official release of Pink Floyd playing a live version of "Welcome to the Machine." All tracks were remixed for the 2019 reissue.
Delicate Sound of Thunder reached #11 on the Billboard 200 and is currently listed as Triple Platinum in U.S. sales — it was certified Gold and Platinum on 23 January 1989 and Triple Platinum in April 1997. In Canada, it was #57 in the 1989 year-end chart.
Delicate Sound of Thunder became the first album to be played in space, as Soviet cosmonauts took it aboard Soyuz TM-7. David Gilmour and Nick Mason attended the mission's launch.
