In The Pathologist's Report, drummer Ken Owen states that he considers Swansong the ultimate Carcass album.

[2] The disc art is the "Unfinished Pyramid et al." from the Great Seal of the United States, but it reads "carcass" instead of "annuit coeptis", "somnus pecunia cibus" instead of "novus ordo seclorum" and "MCMXCV" instead of "MDCCLXXVI".

On 21 July 2008, a twelve-panel digipak version of the album was released, with full artwork and lyrics as well as a limited edition sticker sheet with classic Carcass motifs.

The reissue also features the previously Japanese-only bonus track "Death Rider Da" which was made to be used as a jingle on a Japanese critic Masa Ito's radio program at the time, as well as the fifth and final part of the extensive interview The Pathologist's Report on a dualdisc.

In November 2013, Earache rereleased Swansong on full dynamic range vinyl in different colours and with limited circulation.
