The PSB's
Disco isn't considered a studio album per se, because it's rather a collection
of remixes from their first album, Please.
Disco was
released on 17 November 1986 - 8 months after Please. All it's tracks were
recorded in 1985-86 and are remixes of songs which appeared in Please (4 from
the album, 2 from b-sides).
They are all extended and offer a glimpse to the more
techno-y sounds that the band will release later on (especially Relentless,
which is a bonus CD on one of Very's edition, more on that in due time).
