Bands whose best track* is the first thing you ever heard by them
I think, as much as I genuinely love almost everything that FOTL have done, I still come back to 'The Lord hates a coward' more than anything else in their back catalogue. It just totally reminds me of the excitement of seeing them return, charged with anger and a desire to push on creatively. It's still awesome now and sounds immense.
