I mixed this album on my laptop. Which surprised me.
The drums were intended to be replaced. But I thought the snare sounded okay. The tom sounds are nothing to write home about and before we release this album they still might be replaced. But the snare sound was perfectly decent.
The kick? Well we were never thinking we'd keep the kick but... I mean I just threw a mic inside the kick drum to use as a trigger. So after a bit of EQ and a bit of compression I... I may have shifted the pitch down a fourth to make it sound better.
We improvised the entire thing from start to finish but we were thinking "this is the first movement, this will be the second movement" etc. and we decided on keys and (sometimes) tempos and time signatures. I was very happy with my own guitar sound thank-you-very-much.
I did another thing -- I did quite a bit of editing. Actually, I made exactly zero structural edits (so far) but I did do things like cut out instruments selectively.
