Between 1993 and 1995, a series of unofficial psybient/trance/chillout remixes of Pink Floyd albums were released out of Germany. As of 2019, it is still unknown whom was behind these albums, though it has often been rumoured to be a creation of The Orb, due to a similar production style used by that band at the time. Other candidates include Jimmy Cauty (co-founder of The Orb and The KLF) and Aphex Twin; all of these artists were also sampled at some point throughout the series. Trent Reznor was also considered as the producer at the time of release, but this is apocryphal and the albums do not contain any hallmarks of his composition or production styles.
It should be noted that while other "trance remix" albums of Pink Floyd came out between 1994 and 1999, they are not considered part of this series, either because they embody a completely different production ethos, or because they credited the remixing artist (either outright or through a one-off pseudonym.)
In January 2021 "The Orb Music & Remixes" group on Facebook revealed that:
"It was a guy from a very dinky town in Italy named Massimo Palumbo who called himself DJ Fish in the raver scene but he wasn't a DJ -- he threw raves. I met him through a mailing list on the old hyperreal.org website at the time around 1992, before he made those discs. He worked at CD Company Italy as a contract writer and he worked with a lot of unofficial labels like Great Dane during the brief window in 1993 and 1994 where there was no law regarding unofficial releases there, and those items flooded the import sections of larger shops and you would have discovered them."
