Hey there,
it's your lucky day, apparently -- we seem to share much of the same taste, AND I'm organized.
 
Here's my preliminary list, picked out from the "Confirmed acts" thread. Ofc some may play concurrently, and I personally don't intend to not sleep for 4 days straight, so some might need skipping, but for what it's worth (sorry tabs were lost in pasting):
