Welcome Back: Kamelot
They may be insanely over-the-top, but Kamelot play rebel metal for the masses.
Pure heavy metal, the kind with melody front and centre, and the sort with actual singing, not growls, shrieks or whatever noises Mike Patton is making this week, often gets pigeonholed as having ludicrous lyrics about, like, dragons and stuff. Luckily, the reliably excellent Kamelot not only live up to such expectations with shameless aplomb, but are in the habit of doing it rather well indeed.
The Florida-based, multinational metallers are equally happy to embrace grand literary concepts (they did do a two-album cycle based around Faust and Mephisto), philosophical contemplation, or discuss more tangible real-world subjects.
