[5] At Krieg's show at Die Festung in Bitterfeld on December 8, 2001, Imperial dedicated his set to Kanwulf of Nargaroth,[6] who was beaten up by NSBM band Absurd's vocalist Ronald Wolf Möbus for threatening to kill the latter's son (who was about one year old at the time).

The band's frontman, Imperial, was inspired to form Krieg by "[a] need to express the emotions inside me, which were empowering, crippling and consuming.

[10] Beherit, Archgoat, Darkthrone, Forgotten Woods, Demoncy, Judas Iscariot, Lugubrum, Pest, Satanic Warmaster, Black Crucifixion, Hellhammer, Burzum, Profanatica and Havohej "have assisted in forming my music background", whereas influences "in the non traditional sense I am extremely influenced by Lou Reed's 'Berlin' album, The Velvet Underground, The Stooges, Danzig/Samhain, early Laibach, Incantation (only with Craig Pillard), Earth (us), and a lot of fucking doom".

[3] Rock Hard journalist Björn Thorsten Jaschinski called Krieg a productive band and described their early works as chaotic, sloppily played black metal inspired by Profanatica and Havohej.

[12] In his introduction to an interview with Lord Imperial, Ryan Harding wrote that American black metal bands are "arguably at our best when following the chaotic standard established by the likes of Beherit and the raw evil of Profanatica, as demonstrated by Demoncy and, of course, Krieg".

[4] Compared to earlier releases, The Black House, "whilst equally aggressive, leaned towards a more groove laden and some might say accessible approach", though "[t]he caustic primitivism of […] early recordings is still very much inherent".

[9] The album's lyrics deal with "the dissection of my psyche", rebellion, "descent, anger turned within", "one way to envision how death feels from the perspective of the dying", hopelessness/helplessness, betrayal, sexual depravity and murder without the burden of conscience.

"[9] According to Blabbermouth, Blue Miasma "is the longest KRIEG work — with a running time of about one hour — and continues to explore different moods and atmopsheres [sic!]
