This marked the first domestic USA release for most of the band's output, as only the debut, "It'll End in Tears", had been released in the USA previously.

This Mortal Coil: This Mortal Coil was a music collective led by Ivo Watts-Russell, founder of the British record label 4AD.

Including the singles "Peek-a-Boo" and "The Last Beat of My Heart", the record was a commercial success, peaking at No. 68 on the "Billboard" 200 chart in the week of 3 December 1988.  It spent a total of 20 weeks on that chart.

Two key songs were performed by Elizabeth Fraser of Cocteau Twins, including Tim Buckley's "Song to the Siren", which reached #66 on the UK Charts when released as This Mortal Coil's debut single a year before the album.  The song remained on the UK Indie Chart for almost two years.  Fraser also performed on "Another Day" by Roy Harper.  4AD would go on to release two further albums under the name of This Mortal Coil: "Filigree & Shadow" (1986) and "Blood" (1991).

This Mortal Coil (Redemption album): This Mortal Coil is the fifth studio release of the progressive metal band Redemption.  The album was officially released on October 11, 2011.
