Oh yeah, and something else about White Rabbit (I know its a little late just that I'm listening to it right now and it reminded me) - I think its dark enough because I wasn't going for the ultimate darkness or anything with it, I think its serving me pretty well as it is in terms of what's emotionally driving it from my end. I think the one thing I could probably improve is that main melodic synth that comes in later in the track - I'd really want it to sound more glassy and like a huge ring rotating on edge, I'm all about the visual incorporations and that's what I love so much about drum & bass, not just the visual aspect but the kinetics, kinesthetics, and textures (on top of give-you-darklight-chills melodies). Like I mentioned, White Rabbit is about tripping but its the profoundly spiritual edge mixed with the paranoid. It's that feeling when your way up, that mystical sense, that feeling of connection with something far greater than yourself, that connection you feel with your buds like your all in on something far greater than regular people can fathom (yeah your f'd up and you know its not particularly true but that sort of emotion in and of itself is something priceless and just thinking about it sometimes brings tears to my eyes).
So yeah, its just moderately dark, the heavy base-kick is kinda the only real fear and paranoia, that and I really wanted to get a dynamic going with the snare like to make it sound like the snare's swinging down hard like a sledge-hammer driving railroad spikes (if you want a real good example of the drum beat I was modeling a bit listen to Ed Rush & Optical - Alien Girl, I wanted something like that but even more pneumatic). The rest it just euphoria, timelessness, the ancient and mystical meets the now, pround emotional revelations about your life and existence in general, etc. etc.. The melody is designed in and of itself to feel like your diving off, its that falling pattern.
