I was thinking about Radiohead and their recordings last night. I've seen them live three times now (back-to-back nights in Toronto as well when they only played about 3 of the same songs across each set!) and I definitely appreciate their live sound and energy. They're touring veterans, and it shows.
However, I can't help but think that Nigel Godrich is an X-factor in the Radiohead sphere (they don't call him the sixth member for nothing, though I suppose Clive Deamer is maybe the sixth member now

). The way that Nigel is able to get away with using compression and insane amounts of EQ is pretty astonishing. The result is records that sound quite modern in the sense that they can compete with hip hop records in terms of their weight and punch, yet the instruments retain a natural character. Just listen to the drums on Nude, for example. Of course, all those nice mics and good miking techniques, world-class consoles, and tape go a long way ... but he knows how to make it all work to great effect.
Anyway, just a small random musing. Nigel continues to inspire me.
