I have been a BDN fanboy for many many years. I like the "ambient" approach the most, and find little fault with anything from Pain In Progress to and including Necrose Evangelicum. I can't really pick a favourite between those, it changes with the days. Innerwar and May All be Dead are great too, but not quite as good, I think. After that, I don't really listen to any of it. I have bought all the releases, listened to them a couple of times, then just archived them. That is often the case with old bands. You listen to their new album, think "not too bad, but no new classic" and that's it. Same with Death In June and Current 93 for me. Bands I used to eagerly collect but their records are now just sitting on the shelf apart from the classics which get the occasional spin. I am happy that Roger is still touring though, and for that reason alone it is good that he still makes new music. It is a bit lame when bands tour without any new output. The Primitive Perversions box was a hard listen for me, so amateurish, but interesting to see some of the seeds of what would become great over time. I doubt if I will ever put any of the LPs on a gain though. The Lille Roger box was way better and has a lot of classic material, but also material that i had never heard except for old mp3 rips. The sound quality is way better than on the old Lille Roger CD on CMI.
The CMI label was hugely influential on me as a teenager, so I can't really be objective here. Pretty much everything they released from the beginning until c. 2000 was pure gold, even the more synth cheesy stuff like the various Mortiis and Raison D'etre side-projects. Only band from that period I have never become friends with is Sanctum. After 2000 CMI coulnd't really keep up, but some good things such as IRM was still released. CMI was a particular era for me, and remain close to my heart.
