the 'art' part of songwriting, is finding the method that works for you, and it does not matter what anyone else does.
don't force it, just find it.
-- Hahahahahah! Well spoken! This is a great topic that all of us struggle with.
I couldn't agree more with Bat!
Methinks, studio-engineering of performance-art is a tricky business. Here's my personal quirks on creating song-creatures (and may not work for others):
Reminder: its best to concentrate on creating a new creature in the studio ... lest you fall into the stereotypical garage-band snare. Its time to think more in terms of selecting 'samples' and less on selecting 'performances' ... like an artist ... but much more creative than an artist.
Besides, perfecto engineering of live performances requires a great expensive force of mics, studios, production engineers, etc. Some commercial recording studios claim they can approach this. But the results may be stereotypical, IMHO ...
unless you go home with all the tracks recorded by the commercial studio.
Then its time to spend some additional loving care that the hireling producer won't. Like: Manual compressions, LCR panning, Transient shaping of bass and drums, Haas fx's, reverb, gel, beatz and grooves, etc. etc. ... whatever the new song-creature requires to your ears and the ears of your target audience.
I have found that the beatz-meister wins the day ... especially for the metal drummer. I'd get at least 8 stereo-mic layers of his samples and make his percussives snap, crack, and pop in every conceivable manner ... succinctly and professionally. Expect that alone to take an inordinant amount of time ... like 40 hours.
Then I'd let my faith finish the beatz (with your wild vision) and not finish the song til Danzi or someone has reviewed the beatz.
Invariably, home studio-art must win the day: Like a portrait painting of another's portrait painting ... a new creature twice removed from the original song-creature ... a different and much greater animal ... hopefully immortal.
IOWs, its better that you alone must now play producer and decide your protocols ... from song creation to song print ... with recordings spattered everywhere in-between. But the drums had better get real.
The words of Yep and Yoyo might apply: "Finished is better than perfect"
Like ... urgently get the track samples recorded onto tracks and take it from there ... retake, re-perform, and re-sample any way you desperately can.
