A Thousand Suns is most definitely Linkin Park's Kid A.
Well, maybe not technically, but, at the very least, spiritually. Like Kid A, Suns is an album of great ambition and equally great scope, a fearless effort that takes the band to places they've never been: darker and doomier places, louder and (in sections) heavier places too. Like Kid A, it is so completely different from the band's previous efforts that it will almost certainly stand as the line of demarcation between everything that came before and everything that will come after. And, much like Kid A, there just aren't a whole lot of guitars on it.
