It’s tricky because there is so much classic thrash on here, but that genre died and was revived and then died again. If you get a taste for death metal or some of the other more contemporary extreme subgenres it’ll be easier to follow current bands and see them in the future.
Here are a few modern recommendations you might like:
Unto Others (fka “Idle Hands” ) - Mana
Tribulation - Down Below
Blood Incantation - Hidden History of the Human Race
