on the one hand there are some interesting layers to each of the parts and these seep into the corners of your mind and slowly begin to hypnotize you. more layers slowly appear and you find yourself pulled further under. i found this to be quite a relaxing release hovering somewhere between drone and ambient, but on the other hand all the little riffs/strumming sections and all the other nice textures are looped over and over and over (especially in the longer songs; there is a more free flowing nature to the shorter songs) and while it is quite relaxing it's still a repetition. perhaps it could do with the occasional octave change; perhaps that would ruin the relaxing nature of the songs.
the layer build ups are quite slow in their appearance but once they've arrived they stay until the end. the forward momentum part one has a bit more variation and it's the shortest. part two is very relaxing; perhaps the drone is a little harsh but the two overlaying riffs play well off each other. part three is the longest track and suffers from a slight timing issue but there are some interesting experimental sounds. part four is the most expressive and again quite experimental making good use of this instruments.
i am esper is interesting, i feel like he's still trying to discover his sound but once he finds his niche he'll probably experiment his way around it. some people will like this some people won't; i did quite like this so i would recommend it.
