Did the necessary recombinant audio on "Little Computing Machine" and "Mushrooms". That involved combining partial tracks into single tracks so as to make them easier to process, then adding reverb on the lead vocals.
Splitting and combining clips is a lot harder than it ought to be, especially with the new stuff in Audacity 1.3 that supposedly allows them to be moved around independently. At least, after you do a paste, you can slide the pasted clip around horizontally so you can eliminate the gap that you have to leave to avoid undoing a previous cut. There must be something simple that I'm missing. I've never been able to synchronize cuts and pastes between different tracks. I would have expected it to involve the ability to drag or select a clip, but I can't find a UI element that would let me do it. Well, it is beta software.
Still needed: guitar and percussion on "TEOTW...", effects on "Vampire Megabyte", tweaking, and layout.
