In the past couple weeks:
All That Remains: 10/10 - longtime friends and their late guitar player was my teacher for a short period way back in the day. Been seeing them forever and always a fan, though any fan of the band knows they've had a run of softer albums in recent years. But their latest is absolutely awesome, and the current tours are heavy as hell with some surprising old gems. It'll never be the same w/o Oli Herbert, but the replacement is a star in his own right and should hold the position well. Oli's on-stage persona was something else, especially if you knew him and how completely opposite he was. Part of what I loved it!
I've seen them on almost every single tour in the past ~20 years since they were just doing local gigs, and even if a couple songs are weak in the past decade or so they have always been better live. This was definitely one of the best sets I can remember in a great number of years. If they had a couple of my heavier favorites included, it may have been the best set of theirs I'd ever seen!
Children of Bodom 8/10: another band I've seen way more than any sane person. They were tight as always and the setlist was pretty solid except a lack of OLD stuff. But their tour from last was all old stuff (half of that being REALLY old stuff they never play), so I can't complain too much. Too many of the new ones just don't do it for me, but I had a good time as always. If I suspected I wouldn't, I wouldn't keep going.
Metallica: 10/10 they can't do wrong, come on now. I was 5 feet from the stage and got to hear a couple songs they didn't play on the 1st part of this tour 2 years ago, plus one of my favorites, "Blackened" which was a treat as they rotate that one in & out on a nightly basis. Jim Breuer was the opener as a host/emcee and he was cool. Seems most didn't like him but I thought it was more entertaining than most opening bands I have no interest in. To be fair, on the last tour I did like both openers (Avenged Sevenfold, though I am not a fan I didn't mind em; and Volbeat (I couldn't name many songs but I usually enjoy them, and their set was great).
Only complaint here was that the crowd on the floor was LAME, just standing and no rough-housing, which made for a very sore back. Oddly, I get more sore standing in one spot than fighting and throwing people all night. I'm just used to small clubs and showing kids who the OGs are. I also got a pick from Kirk at the end, and you can't hate that.
