Black Secret Technology is the fourth album by UK electronic producer A Guy Called Gerald, released in February 1995 to widespread critical acclaim.

'"[3] In a 1995 review, Andy Smith of The Guardian proclaimed that Gerald was "among the first of his peers to corral [the genre] on to a satisfying album" as he had previously done with acid house, calling it "enthralling".

[14] Discussing the 1997 reissue, Ian Harrison of Select stated that "there're few records in this fast-moving genre that could sound as good as this does now," adding that "the album will one day have him listed among Sun Ra/Lee Perry/George Clinton cosmic clubhouse of interstellar visionaries.

"[11] In 1999, Tom Ewing of Freaky Trigger described it as the "best jungle album ever", stating that Gerald "latched onto a more turbulent tradition, the jazz-funk-electronica of Pangaea-era Miles Davis or Sextant-era Herbie Hancock, and the music he made boiled like theirs.

[15] In 2010, Fact magazine ranked Black Secret Technology the fourth best album of the 1990s, calling it "gloriously knotted, soulful and uniquely psychedelic;"[16] Fact critic Mark Fisher wrote that the album "succeeded in simultaneously being of its moment and transcending it," praising in particular "the way that Gerald transforms the jungle sound into a kind of dreamy OtherWorld music [...]: humid, tropical, full of strange bird cries, seething with nonhuman sentience.
