The major problem seems to rest in a few basic areas: 1) the quality and outlook of the band; 2) the nature of the genres themselves, which while having some similarities--mostly among better groups and projects with similar outlooks--also have major differences; 3) reconciling electronic instruments and effects with the organic flow and melody characterized by good black metal. Electronic music, especially the more intricate variants of ebm, electronic industrial, and various synthpop/futurepop variants can carry heroic messages, romanticism, and ideals similar to some black metal projects easily.
The creative blending of these modes of expression seems in itself to be rather difficult because of the important differences between black metal and industrial music in terms of composition, production, and the way that the devices themselves are used. Many industrial musicians, even the better projects, build their songs around relatively conventional structures like 4/4 drum rhythms, conventional popular song structures, and a relatively rigid arrangement and composition which assists in lending a mechanical touch. However, with the blurring of genres among electronic artists as others drift into very different genres such as trance, ambient, etc. is start to result in more intricate and creative forms in electronic music. Likewise, there are also black metal musicians who have experimented and developed projects in different electronic genres.
Just some ideas to ponder. It is really a statement of the obvious, but a creative mind can possibly overcome them to produce a form of art with elements of both but is neither. Trance inducing, ethereal, flowing, melodic while communing with electronic tones, and atmospheres which do not reduce or conflict with each other, instead bringing a new cohesion. Segmented nu-metal riffing, thoughtless automatic drum programming, and rapcore rhythms need not apply.
Blacklodge seems to have embraced electronics rather enthusiastically but it remains to see if they will rise out of merely being "industrialized black metal." The potential is there in many people, but it only will yield fruit if they pressure themselves to create a new standard.
