Laetitia Under The Radar Interview

Last bit of the article:

...next year should see her follow-up to last year's well-received solo debut The Trip. And as the future of Stereolab, do she and Gane discuss whether and when the band will continue?
"No," she offers bluntly, before adding, "and I'm hoping the band won't resume as we've known it. I hope that I will carry on to one day sing Tim's songs, but that we'll have different people in the band."

Also there's a heartfelt interview with James Cargill on life/music after Trish's passing.
