Do Make Say Think. Now there’s a blast from the past for me. Saw them live a few times and they were great.^^ Was gonna mention Pantera but you beat me to it. Havok is another good one. They have some anti-Christian songs, but I leave those out of my Playlist.
If I'm just stretching for a recovery day, I'll put on some Do Make Say Think. They're instrumental and very relaxing.
