peak blog rock was more 2004-2012
Arcade Fire, Dirty Projectors, Deerhunter, Yeah Yeah Yeah's, Bloc Party, Animal Collective, Ariel Pink's Haunted Graffiti, Broken Social Scene, etc.
2013 was a turning point. Arcade Fire dropped the dance influnced Reflektor, that got mixed reviews. Conde Nast bought out Pitchfork. Hip-hop completely eclipsed rock in popular music.
UK and Australia has a popping rock scene, the states kinda ehhh right now. Indie heads seemed to drift to EDM / House music, ambient/drone or "alt" R&B. Or they love drill music and trap and pretend they never fukked with backpacker shyt like Brother Ali & Company Flow
i think the blog / underground hip-hop started in 08 and peaked in 2015
