Robert Pollard continues to be an unstoppable music-making machine. Suitcase 3: Up We Go follows 2000's Suitcase: Failed Experiments and Trashed Aircraft and 2005's Suitcase 2: American Superdream Wow. The lo-fi maven is once again plunging into his bottomless pit of Guided By Voices demos, outtakes and ephemeral cuts. Suitcase 3, like the previous two volumes, is a four-disc set featuring 100 tracks, many of which have silly, fictional band monikers, such as Erotic Zip Codes and Demon Gods of Anger. The unearthed material covers the mid-90s to 2009, with the fourth disc steeped in acoustic songs recorded by Pollard, Greg Demos and Tobin Sprout during the trio's 1994-95 peak.
