From Mogwai’s mailing list:
Last week we mastered our new album in NYC with Greg Calbi. We have been recording at our new Castle Of Doom studios in Glasgow with Tony Doogan since Spring this year. It is 43 minutes, 7 seconds long. We are very happy with this record, we hope you are too. In a break from Mogwai tradition we will be releasing a single to precede the album.
Sweet! No release date given, though.
