I think it's because they are on a label that doesn't really care.
Despite all the plans that New Order had for the future I think a lot of things started going down hill after the poor sales of Sirens Call. They didn't get much airplay for the album. There were a lot of songs that could have been used in TV and movies. They could have done Saturday Night Live or David Letterman. Shows that are on in every area of the states.
But it isn't all the labels fault. If the band wanted to tour, even if they couldn't fill a huge auditorium, they could have done more festival type shows, or even if they could have gotten an opening spot for a band. Could you imagine what could have been if they would have opened for U2, or Depeche Mode. Not that they have been bumped down to opening band status...
If they would have started a tour during the time that Sirens Call came out, continued through the release of Singles and up through the release of the "follow up" album that was supposed to come out it could have been huge.
But after the slow sales of Sirens, instead of wanting to put out new material, the back cataloge got raided again. I think that Singles was a great idea, however, the casual fan who already ownes one of the several other best ofs that have come out latley really had no incintive to buy it. So the new material isn't catching new fans, and the old material has been "mined to death". So the record label says why do we want another record right away guys?
This has to be straining relations in the band at this point. There was already a lot of apethetic feelings coming out. And then say you have members in the band that wants to get out and tour, and other members who don't for various reasons, like family, or just being fed up with trying to please fans the others in the band and record labels.
I know the band could have done well if they had some support and promotion, both from themselves and the label.Maybe they should have gone back to an indie label. Someone like Sancturary that seemed to at least care about putting music out.
I only hope that sometime in the near future someone can say something that will get them back together again and we have some more great music from them.
