Ooh, good question. One of my favorite bands is Mastodon, they were playing near me a month before my T. I'd missed seeing them twice and thought "ooh, finally I'll get to see them. DENIED.
I also like Powerwolf, Kvelertak, Aborted, Ghost, Snot Royal Blood, Pantera, Nine Inch Nails, Killswitch Engage, Avenged Sevenfold, Cancer Bats and so on and so forth. I'm a bit of a happy clappy type when it comes to metal, there's little I don't like.
