Oh boy, there's a lot to address...
I'm still in progress of ordering my thoughts and ideas for the Liberi Fatali remix so apologies if it's just incoherent blabbing, but I will try to convey what I have so far. The style of choice would be my usual symphonic metal (with experience from these four remixed tracks - putting this out here just in case someone looks at my posted mixes and thinks "I can see metal alright, but absolutely no symphony") with more emphasis on the symphonic part (including full orchestra and four voice choir) and I was planning to stick closer to the source this time around instead of going hipster with the source as I usually do. A rough layout of the song I have at the particular moment is this:
A rather drawn out ominous and menacing orchestral/choral intro build-up with lots of references to the source, slow chord progression with dissonances (particularly in brass).
Guitars/drums/bass come in, tempo picks up, this part is more of a cover/rearrangement of the source with alterations.
A bridge section with various instruments exchanging melodic and con bravura solo sections? Not entirely sure, haven't thought too much about this yet.
Reprise (see point #2), leading to climax.
A rather sudden drop in energy (just like the source tune on its final chord), orchestra closes off the piece.
I am very welcoming to the idea of collaboration because, frankly, this is a very ambitious source to work on plus things I have in mind will require a ton of effort to pull off, so division of work would help a lot. There are a lot of things to do, and just to list a few...
Composition - I imagine this would be a rather step by step process where people can listen to drafts, give feedback and improve the piece.
Orchestra - I am using EWQL orchestral VST, which is sufficient, but there may be better alternatives that other people have. Additionally, if there's someone, who has a lot of experience in orchestral articulation and humanization, his/her input would be invaluable and make the piece a lot livelier.
Choirs - again, I an using EWQL symphonic choirs, but I bet there are great voices out there to fill the role. Or just better choral VSTs.
Drummers/bassists - both of these I usually have programmed, which is sufficient in most cases, but it's always better to have live recordings.
Guitars - guitar is one of my main instruments, but there's really a lot of stuff to record, including double-tracking, solos, solo backings, dives, clean chords and arpeggios, etc. etc.
Mixing/mastering - while I enjoy the challenge and I was getting the hang of symphonic metal mixing recently, it's a huge load of work and require hours to get it right without pushing important instruments into obscurity, I'd be very happy if someone helped out with this.
Ultimately, we would need some kind of place to chat and polish ideas, like an IRC channel, but that can easily be arranged at any point.
Let me know what you think of this plan. Currently I'm on holiday abroad until the 10th and might not be checking for replies every day, so bear with me.
