This is a special edition reissue from 2017, twenty years after the original release. It’s a three record set that includes the original album plus 8 B-sides ,that were on the Airbag EP that I have on CD,and three unreleased tracks.This is Radioheads most critically aclaimed recordings and this will be my first time listening to the entire release. It sounds pretty good to me,some parts are what you might call progressive sunding like Porcupine Tree in some places. Another record I will want to explore some more ,sounds like some good stuff on here.
