Lineage: master->CDR->CDR->EAC->SoundForge (speed correction, some minor editing, re-tracking)->FLAC Frontend

I'm quite certain this is a raw transfer of The Grape's master. Because of the "darkness" of the sound, the question has been raised whether it's been modified somehow. But my 2nd gen tape from the mid-90s turned out to have just about the same spectrum, so it's most likely just the question of a somewhat dark recording.
Suggested disc split between track 10 and 11.
