So...is the argument you're making that fans want the best thing possible? Why is this limited to Kevin? Isn't that what people want from every artist?
In this particular case, I think it's a huge make/break point in Kevin's career with the GDB. This is for a number of reasons, includingh Bad Books getting more traction than he's ever had solo/GDB, the anniversary show, the huge focus on a "guy from this scene" raising $100,000 to record some records, one of which is with the frontman of one of the most popular "underground"-ish bands ever.
As you put it, people do always want the best from every artist they are a fan of. Sometimes, though, the expectations are low, so you can get away with mediocrity or just a "good" record. This isn't the case for KD.
Good luck to him. Can't wait to see how he plans to do tour on / distribute these records.
