For some reason, I bought Aegea. Think I thought it might be good. Then, limited to 500 (?) copies, autographed - sure, I'll kick down $75 or whatever it was. Turns out it's no good, but, hey - at least I've got a fun collector's piece.
That said: with this next one, I know it's no bueno - so really, no chance I'll bite. Plus, a 5 LP set is probably gonna be spendy.
