Lunatic Harness, µ-Ziq's rare and sought-after fourth album, was originally released in July 1997 on Virgin's Hut Recordings label. It is generally considered to be Mike Paradinas's best work of the nineties. An Apple Music review describes Lunatic Harness as "the prettiest album to come out of the mid-'90s "drill'n'bass movement", noting that Paradinas eschewed the abrasiveness of similar works by Squarepusher and Aphex Twin in favour of "atmospheres of ethereal color and shimmering melody", bringing the album "closer to pop music than anything Paradinas had previously attempted".

Planet Mu has compiled a special 25th anniversary edition vinyl 4LP box set bringing together the My Little Beautiful EP, the Lunatic Harness album and May 1998's Brace Yourself EP (released by USA's Astralwerks label) with the addition of four rare tracks. Discs one and two of the vinyl are the original Lunatic Harness album, disc three compiles the My Little Beautiful b-sides with three unreleased cuts from the period and a remix of "Mr. Angry" from 1997's Mealtime compilation, while disc four is the 8-track Brace Yourself EP which hasn't been re-issued since 1998. This all comes in individual printed sleeves housed in a rigid box with an insert collage of some of the press Mike received at the time.
