Diabolical Masquerade was the solo-project launched by Katatonia mastermind Anders 'Blackheim' Nyström with his debut in 1996, though Blackheim had composed most of the music for this album during the preceding few years, to be used in a project separate from the gothic/doom metal styling of Katatonia.
 
Diabolical Masquerade was based primarily around symphonic/melodic black metal as the albums progressed; creating eerie atmospheres through keyboards and utilizing more high energy & technical compositions than those of his main band, with complex patterns of riffs and hooks.
 
Ravendusk In My Heart was originally released in 1996 and stands as a startling debut of fantastic imagery, shaped by accomplished atmospherics mixed with cold black metal, bringing to mind the early works of Emperor, all brought to life with deeply imaginative tales of fantasy from Blackheim's realm.
 
The album was recorded at Unisound Studio in September 1995. It was produced by Dan Swano & Blackheim, and mixed by Dan Swano (familiar for his work with Opeth, Dissection, Marduk, etc)
