single release launched the KLF's minimalist "Pure Trance" series of singles. The "Pure Trance" version is a synthesiser composition based around an acid house riff on three low-pitched notes and one minor chord (B minor). The subtle progression of the piece occurs through the modulation of the main loops, the dub-like dropping of particular loops, and a recurring high-pitched refrain on two notes (B bending to F#). An Oberheim OB-8 synthesiser provided the instrumentation. Two discs of different "Pure Trance" mixes, numbered KLF 004T (green writing on a black sleeve) and KLF 004R (yellow writing on a black sleeve, and a cover sticker), were given low-key releases on 24 November 1988 and 24 July 1989 respectively. The cumulative popularity of KLF 004T in continental European clubs prompted the KLF to release a compilation album of selected cover versions and sound-alikes, entitled The "What Time Is Love?" Story. As Drummond had predicted, the "Pure Trance" release received little attention from the music press. However, upon the release of The "What Time Is Love?" Story, Q Magazine hailed the track as "a whirling house stomper ... not so much of a tune but a good beat". Live at Trancentral A 1990 version subtitled "Live at Trancentral" was the first of the KLF's upbeat "Stadium House Trilogy" and the single that introduced the KLF to an international mainstream audience, reaching No. 5 in the UK Singles Chart. It is a pop-house reworking of the Pure Trance Original, adding vocal samples, a new bassline, a new house rhythm and a self-proclaiming rap (performed by Isaac Bello). The "Trancentral" in the subtitle refers to the KLF's recording studio. Although crowd noise features on the mix, it is in fact a purely studio-based creation and a characteristic of the "Stadium House" recordings. An LP version of this mix appears on the album The White Room. A remix 12", "What Time Is Love? (Remodelled & Remixed)" was released a month after the "Stadium House" version. It contains remixes by Echo & the Bunnymen—for whom the KLF co-founder Bill Drummond had previously been manager—and the Moody Boys. Both "Live at Trancentral" and "Remodelled & Remixed" were declared 'Single of the Week' at different times by New Musical Express (NME), where "Live at Trancentral" was described as a collision of "energy, humour and violence". The magazine also ranked "Live at Trancentral" as the 47th best single of 1990. Q
