Elysium, originally released in 2012, was seen by some as a shift in sound and direction for Pet Shop Boys. Writing for the album began whilst PSB were on tour with Take That, with some tracks dating as far back as 2008. The album was co-produced by PSB with Andrew Dawson, who engineered much of Kanye Wests album 808s & Heartbreaks, a record which Neil Tennant had become mildly obsessed with at the time. The darker lyrical themes of Elysium are reflected in the records sound. Neil Tennant said: It is deep in terms of the sound-got a lot of sub-bass-its sort of deep in terms of subject matter, the way its expressed. But I think its the Pet Shop Boys most beautiful album. The Further listening album of additional material alongside this Elysium reissue features previously unreleased demos entitled Vocal, She pops and In slow motion, as well as PSB mixes and remixes of Leaving and Memory of the future.
