Pet Shop Boys have two albums and a "double B-side" single in the pipeline, and the single features a version of Blur's "Girls and Boys".

The duo are currently in a West London studio working on an album of new material for release next spring by Parlophone. They're expected to work with different producers on the project.

Meanwhile, "Alternative Pet Shop Boys" - a compilation of 30 PSB B-sides arranged in chronological order and spanning the whole of their 10-year career - has been set for July 3 release. It'll be available as a triple vinyl LP, a double cassette or a double CD.

The collection will be preceded on June 12 by the single, which couples the 1986 track "Paninaro" with "In The Night", the B-side of the Boys' debut single, "Opportunities". The Blur cover is a live rendition of the song PSB remixed for Blur's own single. The PSBs' version was recorded on last year's "Discovery" tour and it appears as a bonus track on the CD format of the single.

The tracks on "Alternative Pet Shop Boys" - which originally have the working title "Flippantly" - included the duo's covers of the Brecht/Weill song "What Keeps Mankind Alive" and Noel Coward's "If Love Were All", plus their version of "Losing My Mind", the Tennant/Lowe song that became a 1989 hit for Liza Minelli. The artwork for the compilation features a "lenticular" photograph of the pair, which produces a constantly changing images.

The collection will come with a 30-page illustrated booklet featuring a lengthy PSB interview with Jon Savage.
