My only guess for the brackets part is that ELEPHANT is addressing Casey Jones in side-bar in compressed version of what's going on. ELEPHANT reveals that she is going to jail with Casey Jones, the "carved out hands in our basswood" might be a reference to Bear and Fox (Bear's Vision of St. Agnes, line 1 "wooden sculpture hands"). I haven't thought about it more than that, but the borrowed guitars and fretboards might somehow be references to other animals - saying they've got out safe.
