Yesterday, I was at an all-day death metal show (first band was on at 3, show didn't end till after midnight, there were over 10 bands). I was most there to see Parasitic Extirpation (Mallika from Abnormality also fronts them) but all the bands absolutely killed it. My favorites of the night were Parasitic, Pyrexia (the headliner), and Car Bomb. Car Bomb was the biggest surprise for me.
