Aereogramme has announced, through a MySpace blog, that they've decided to call it quits:

It is with heavy hearts that we tell you all that Aereogramme have decided to split up. Reasons are multiple and complex. It is however fair to say that the never ending financial struggle coupled with an almost superhuman ability to dodge the zeitgeist have taken their toll, ensuring that we just don't have any fight left in us. We are immensely proud of the four albums that we made over the past seven years. We hope that they continue to grow in your hearts.
