This is what we found on Wikipedia regarding the Pleasuredome:

Welcome to the Pleasuredome is the debut studio album by the English band Frankie Goes to Hollywood, first released on 29 October 1984 by ZTT Records. Originally issued as a vinyl double album, it was assured of a UK chart entry at number one due to reported advance sales of over one million. It actually sold around a quarter of a million copies in its first week. The album was also a top-10 seller internationally in countries such as Switzerland, Sweden, Australia and New Zealand.

The album was commercially successful and contained new versions of the songs from the group's singles from the same year ("Relax" and "Two Tribes", plus B-side "War"), as well as several cover versions. Trevor Horn's production dominated the record so thoroughly that the band's own instrumental performances were often replaced by session musicians or Horn himself. Frankie's second album, Liverpool, actively featured the full band.

The ballad "The Power of Love" subsequently provided the group with their third consecutive UK number-one single.

To celebrate the album's 30th anniversary, in October 2014, ZTT through Union Square Music released a limited edition (2,000 copies only) box set titled Inside the Pleasuredome, available exclusively from the website pledgemusic.com. The box set contains rarities on 10" vinyl, as well as a book, a DVD, a cassette (featuring 13 mixes of "Relax" and its B-side "One September Monday") as well as a new 2014 remastered version of Welcome to the Pleasuredome on 180g vinyl.
