I've always thought it interesting how many different styles he has throughout the years. There's soooo many songs that sound like they were influenced by or influenced other songs. Very much like Tangerine Dream in that respect.
I like most of it, probably the ones I like least (a relative thing) are the ones where he's doing too much playing around with technology and sampling loops (but only because I've heard too much of this type of music over that last decades).
Like I said, I hear so many other bands in what he plays (like Tangerine Dream, Roxy Music, Gary Numan, Brian Eno, Art Of Noise, Japan, etc., etc.), but I LIKE all those bands! It's been a long time since I've played his material and I'm playing it the same way that I used to: as one big playlist, so it's hard to associate songs with the albums they're on. That said, of his early stuff, I like the Red Noise (BBD to solo transition) album Sound On Sound (which is where that online magazine got their name from) and Chimera (which is a bit more upbeat and musical than a lot of his ambient efforts).
Too bad I'm trying to do some tutorials right now. If I was just working on the PC these could be playing all day and night in the background - lol.
