I absolutely love Radiohead, and with MJ, their music never gets old!
To this day, when I lite up for the first time after a long dry spell, I always time my first hit to the opening of Kid A and just let the vibrations carry me into a long and blissful high.
I've seen 'em live on three separate tours... they keep getting better. I agree, their light rig for the most recent tour was pretty fucking amazing.
I shared Radiohead with my classical-music-fascist-grandma, Strung Out on OK Computer a string quartet interpretation, and even she can appreciate their melodies and harmonies.
