I could never get into Dreamtime Return because I really dislike the sound(s) of it.
But I do like, or love, most of his other stuff so far. I must say I do prefer his more 'active' music.
'Darkest Before Dawn' is definately too much for me. Or better said, too little. Too little substance. I just can't listen to such still, repetitive and minimal atmospheres. Maybe only as background sound.
I absolutely love Magnificent Void (IMO his all time greatest beyond any doubt), which is more like 'maximal atmospheres'. Although it took many, many listenings before I felt that way.
One of my favorite recent works is Arc of Passion, especially the first half of the title track (I think it's better than anything on Landmass, although I like that one too).
The warm sounds, the beautiful emotional chords, the rich and detailed sequences, the smooth build up. Seriously, this piece reaches a PERFECT momentum at some point. You will know when.
Anyway, maybe the best starting point would be Kairos. A fantastic 'showcase' of his music (mixed/edited material from various previous releases + some album-unique sounds) and u get great visuals with it too.
