This one came together kind of unexpectedly--I'd wanted to use my new(-ish) acoustic guitar, a size 2 parlor guitar from Vintage Parlor Guitars. The unexpected bit was that the first rhythm I had in mind worked best with a simple kit built up from Ableton's Operator FM synth--so the track first seemed to have a kind of Autechre direction. I threw in some Operator bass, and some Simpler with grand piano and prepared piano samples, and put in a return channel of convolution reverb with the Fort Worden cistern impulse response.
While I tracked several electric bass lines, I didn't end up using them--they weren't quite working with the rest of the track.
At the end, I impulsively put acoustic guitar in the second half (recorded with a Karma Mics condenser-in-XLR-body), and it pretty much worked, especially with some normal-room convolution reverb on a send. There's also some Waves Factory Cassette plugin on the grand piano. I'd initially had it on the guitar, but it just mainly made it sound bad.
There's some Full-Chain Master on the output, a bit of automation to the sends, and an additional send with Ableton Echo. And that's about it.
