I started with just the very first riff you hear.
Then I just kept adding and adding and adding and ....
I. COULD. NOT. STOP. MYSELF.
SO. MANY. LAYERS. OF. ROCK.
I really want to do some detailed notes on this before I forget.
1952 Blonde Tele Reissue - Neck Pickup - into my Crispy Creme Custom pedal set on all distortion, tuned down to D
I hard panned two tracks of the drop D guitar, left and right.
In the intro of the song the feedback was me leaning in next to the amp on ANOTHER track just getting various types of feedback to use in the intro and outro.
Once I got the guitars done, I added drums. Just a really simple, as hard as I could hit them, but simple, track. I do Glyn (sp?) Johns mic'ing approach. Two overheads mics equidistant from the snare and kick.
Then I added some bass. I had a HARD time taming it with all the distortion I had on it...but I kind of liked it, so I left it as I did it. I also DOUBLED the bass an octave higher. THAT track was much cleaner with no or little distortion.
Then I added some lead guitars that squelch out during the little breaks in the second half of the riff.
Then I added acoustic guitar, because I was super inspired by @downfallroad's awesome heavy acoustic riffs. I d-tuned the acoustic and did two tracks and panned them about the middle of left and right.
So, after all this I still wasn't happy with the "big" section (the second half where it all kicks in). So, I just started adding things in. I actually have vocals (maybe you can hear them?). I doubled each vocal part AND even through in a whistle towards the very last couple of measures - all doubling or octaves of the main riff).
Also a tambourine lined up with the snare.
