12 years ago I saw Immortal, at the peak of their powers, smashed in at a small club outside of Chicago. For perhaps the only time in my life, I left before the headlining band came on, confident that the only role they could play would be to sour the high that I was on. That headlining band was Manowar, and this thread is yet another confirmation that my decision that night was the correct one. So thank you!
Your situation sounds like a nice mirror-image of mine; rather than pre-emptively avoiding a bad taste in your mouth like I did, you instead used Dark Tranquillity as mental Listerine. Nice work.
I can also add that the ticket price to see both Manowar and Immortal back then in 2002 was $20. Sorry.
