When Swedish death metal supergroup Bloodbath released Nightmares Made Flesh on September 27, 2004 via Century Media Records, the album marked a pivotal moment in the band's evolution.

The record was the band's second full-length release and remains one of its most distinctive, thanks largely to a unique lineup shift that introduced vocalist Peter Tägtgren and drummer Martin Axenrot, who later joined Opeth as their longtime drummer.

Despite his commanding performance on the album, Tägtren clarified in a 2005 interview that he was never a permanent member of the band.

Nightmares Made Flesh would become Dan Swanö's final album with Bloodbath.

The album is known for blending classic Swedish death metal brutality with a sharper, more modern edge – cementing Bloodbath's reputation as one of the genre's most formidable supergroups.

One unexpected cultural crossover came when the track "The Ascension" appeared in a two-part European episode of the MTV series Viva La Bam, where Bam Margera and his family traveled across Europe.
