Mastodon, I caught them live probably more than 10 years ago now, but didn’t get into it at the time
I can totally understand that. Their sound quality tends to be inconsistent in live venues and at times poor, especially in the more distant past, but def trending better these days and the last time I saw them (Oakland Fox) was the clearest I've ever heard it. Plus the older stuff was all jus so heavy, but now there is much more variety to the sets and more melodic material. Anywhoo... not to sound like a goofy fanboy, but they are friends from our old neighborhood in Atlanta, so it's always great to see talented nice guys work hard and achieve well-deserved success over time.
I really appreciate the other suggestions from Kickstart and others, as I agree it is hard to keep up with everything coming out.
