My experience with this show was more like what you referenced. Having to sit through In Flames after Hatebreed was one of the most painful concert experiences I've ever gone through. Not only did it kill the energy of the crowd, people were just standing there like statues. Other than Marilyn Manson trying to play after Slayer, this would be the 2nd worse band slotting that I've witnessed. To me Sylosis blew In Flames off the stage and is everything In Flames should be. Sylosis are awesome and incredible live.
Maybe it was IF's setlist too. It started off so weak that they lost most of the crowd 2 songs in. I'd rate this show:
In Flames 2/10
LOG 9.5/10 (just because they could have played longer and should open with Straight for the Sun or Hourglass)
1/28 - Machine Head
3/3 - Hell Yeah
3/31 - Coal Chamber & Filter
