Not as in:
Desultory was part of the first wave of Swedish death metal bands, alongside Entombed, Dismember, and others. Into Eternity, their Metal Blade debut following a lesser-known EP release, is standard for the genre, energetic and forceful, straddling the line between the more brutal American death style and the melodic Gothenburg variety.
