Proposed double-album
I have 3 hours, 9 minutes and 54 seconds of material to put together for a double-album. The 1st step is to edit it down, then the real work begins with recording, adding instruments, mixing, et al. 

Aphex Twin's 2001 double album; Drukqs was a wapping 100 minutes long; ie. 2 CDs or 4 vinyl records!!!!
