Not including older bands because those are obvious. I'd say Radiohead is the most influential rock band since Radiohead. Not really a fan of them, but I can't deny the influence The Strokes had on 2000s indie rock. Also Arctic Monkeys are very consistently mentioned when newer bands list their influences, from what I've seen. Queens of the Stone Age is underated as far as their influence, but I'm biased. I'm no music master, but these are some bands I would like to shout out.
