Even if i don't know all of his works by far, i've been listening to Mr. Dangers every now and then for more than 15 years now. And I still like his music, even if my personal taste changed a lot since then. In my humble opinion, that is what few artists achieve, to consistently deliver high quality output throughout such a long time without getting boring and repeating yourself too much. Even the older stuff doesn't sound dated to me, i can still listen to "99%" (released in 1990!!) and it's still great.
Mr. Dangers has a few trademarks: his excessive, but clever & skillful use of samples, his beats are always groovy like hell and so are the basslines and that is already the essence of his tracks, which are just perfectly built from these parts.
i can't really estimate how popular he is, but it seems to me that he's quite underrated. The last live performance from MBM I witnessed here in Berlin a few years ago had a crowd of maybe 50 people, if at all, and it was the only show in Germany!! Nonetheless they (Jack Dangers + ??) did a great performance containing perfectly synchronized video parts accompanying the music.
Maybe the dilemma of MBM is that it never totally fit in one genre, ranging somewhere between their EBM roots, strong breakbeat & dub influences, even hip-hop orientated stuff, I have the feeling that they never reached the larger audience they deserved, at least here in Europe. That's just my personal view, altogether it can't be that bad if Mr. Dangers is still putting out his great "sampladelic funk" & developing his style after almost 25 years, besides being a highly respected producer & remixer for a lot of acts and projects.
