Lange has produced some stunning tracks in the past, the likes of Drifting Away and Sincere. Both of these appeared on a his 'History' CD as part of the Better Late Than Never album which came out last year, which indeed made that album excellent. His new stuff on BLTN was probably slightly better overall than what we are presented with on Harmonic Motion.
This is not a bad album - there isn't a bad track throughout, and Lange has created his new genre and is admirably sticking to it. It's different to his late 90s/early 00s harder trance which personally I preferred - his tracks then had more bite and passion about them, or at least that's how it came across. None of the tracks lift off for me on Harmonic Motion, they seem to lack that spark and completeness that some of his earlier work did. As a result I was left a little flat by most of the songs, and personally there were too many tracks with vocals on (although this is just my taste - AND Lange has always been a fan of vocals, as Drifting Away and Sincere indeed showed).
Like I said, none of the tracks are bad and it is easy to listen to, with a mix of ambience, some electronic/housier stuff and some non-hard trance. But Lange has high expectations and I was just hoping for a bit more.
