No replies yet? I shall change this!
Track 1: I really like the choice of instruments, very threatening. The main strings sound like they've been run through a pretty tight flanger, makes them sound quite disturbing.
The sawtooth bass later on is a great match for them too. What I'm a bit torn about is your use of dissonance - I'm quite sure it's very much intended and it does serve its purpose of creating a menacing atmosphere, but it still feels a tad overdone at some points. Just my two cents, though.
Track 2: Quite similar in style to the first track and very, very diverse - mostly quite adequate for a battle theme, but later on sometimes too minimalistic to be suitable any longer. The part from 7:00 on is breathtaking - what's with the little break right before, though? This part is definitely not a battle anymore, this is almost Castlevania corridor style, wrenched through a psychedelizer. :D
Nice stuff, all in all, very experimental!
