I've recently just got into them, but there guitar player is one of the most talented I've ever heard.
So is their drummer, Danny Carey. I recommend listening to just about all of their songs, and not just the more popular songs, though to get more of that "full album experience". 10,000 Days is a really good album.
You guys clearly haven't heard me play guitar or drums. xD Nah, I've been told I'm way better at singing.
