They've also been doing this for 20 years, and have done 180s on their sound with virtually almost every album (with the exception of Meteora). They've dabbled in EDM and other 'uncommon for LP' genres through remix albums, EPs etc...honestly there's not really much more 'ground' to be broken. Apart from making some totally artsy fartsy avant garde album with zero song structure, that drones on for like two hours...the band has basically done a lot. And as you correctly said, the band has always followed a song structure. It could be argued that they did that on ATS too. I just don't know what more people want here.
