Bivouac were briefly interesting. I certainly liked this track, but seem to remember that the album, Tuber, didn't hold up that well.
Further research has suggested the Paul Yeadon of Bivouac is / was a member of AC Acoustics and have worked with Pitchshifter. I can't confirm any of that though - anyone know anything more?

The album didn't stand up, so no replacing going on here.
