I'm going to add to this a band no-one's heard of called Audiogene.
Now often a band will break up and fans will be upset, saying things like 'they owe us, we bought their records' or something to that effect. I think this is bull, with Audiogene being the exception.
They released two albums between 1999-2002, when they had to change their name from Bottlerockit (I know, awful name) to Audiogene (slightly better, but awful). From 2002 onwards, right up until their breakup, there were rumours about the third album. I've seen them live more than once; they had tons of material, fantastic material. Some of it came out on the self-titled EP, or the white-label CD. They even occasionally claimed to have almost all of the album recorded.
Then they broke up. Still the rumours persisted; they'll release the album on the net, just for the fans, or something like that.
Three years on, I'm still waiting for that album. I still think they owe us. We bought their merchandise, their records, we went to their shows, we waited for them to release that album, and it never arrived.
