The double album Will And Testament contains live and demo recordings from the later period of the band that was active from London during much of the 1980s.

The live recordings - including private recordings of a concert in Amsterdam's Paradiso in December 1987, considered by the band members themselves to be one of their best and most intense performances - completely different from the only official live album In The Hothouse (1985) and even contain two unknown songs.

The demo recordings consist of four unreleased songs. Will And Testament was composed by The Sound drummer Mike Dudley who also wrote the liner notes and supervised the superior mastering of the recordings that sometimes needed a lot of polishing. After The Sound's most famous album From The Lions Mouth (1981), the double LP and CD got another painting by Briton Rivière on the cover.
