Every age has its conventions that set a target for those who aspire to success. When they achieve a fulfillment of those conventions, the aspirants have entered the elite and expect great reward to follow.
In our time, “progressive” rock has returned with a vengeance in the metal/hardcore world. It takes two types; the avant-garde type cycles between radically different riffs in an attempt to open the mind through contrast, while the jazz-type builds on a jam and then breaks it up with contrasting riffs to keep the jam going without becoming circular. De Profundis is of this second type.
What comes to mind when hearing this record is that Cynic and Atheist put their second and third albums into a room and nine months later, out popped De Profundis. This band mixes metal riffs of several different types with a cocktail jazz ambiance and plenty of delicious lead guitar, but builds up tension and release much like a hard rock band from the late 1980s.
The result is very easy to listen to. The jazz format is the most efficient for musicians, as it doesn’t require creation of custom song structures like other prog does, and it absorbs basically anything you can throw at it. De Profundis throw everything in there, from Satriani-esque quick pentatonic runs to dark minor key improvisation, and the result will enthrall people who like a high degree of internal contrast in their layered music.
Like dub or a really free-form jazz jam, De Profundis songs revolve around a central conflict that encounters interruptions which lead back to the theme. It’s the interruptions that are the main course, ironically enough, because these allow extended rhythm leads and leads that showcase the playing skills here.
It’s a slight to this band to call them “metal,” because it’s clearly only one of several dozen ingredients, but a wide diversity of metal riffing can be spotted here, from Swedish melodic to early black metal. All of this fits into a funky, warm, jazzy exterior that fulfills the expectations of its age’s elites.
