Alrighty, well in my opinion, modern prog is the best corner of the rock and metal scene today. Vola is the newest one I can think of, but there's also Haken, Caligula's Horse, Leprous, Anathema, and a bunch more. Gojira and Mastodon are two of the biggest metal bands at the moment who are actually good. I also love post rock and neoclassical stuff from the instrumental side of things. Post Rock has names like Lights and Motion, Mogwai, Swans, Collapse Under The Empire, Explosions In the Sky, This Will Destroy You and more. My favorite neoclassical artists are Balmorhea, Olafur Arnalds, Max Richter, and Luke Howard. Breaking Benjamin, Chevelle and Deftones are some bands I've enjoyed for years
