K-5, FA43 & 77 and a K50 f/1.2 @ a gig

Been remiss with my photography hobby in the last year or so, I would take the odd few shots here and there but not as often as I used to. I have a feeling that it is down to my K-5, I have not bonded with it as well as I had with my K20D. I just don't trust it. Anyways I decided to spend a day out in town yesterday just taking pictures and ended up in a gig with 2 bands playing high energy heavy metal. My ears are still ringing

ISOs were from 3200-12800, I started off with the K50 f/1.2 for the first band, went to the FA43 on the second band and finished up with the FA77. Aperture was between f/2.0 and f/4.0 on all shots (down to my distrust of the K-5s AF and because I could not make out the focus indicators on the Katzeye, it was pretty dark)

First 2 up are my favourite of the night, they are dark, moody and yet give a feeling of how the night felt:







First Band:













Second Band:
















C&C welcome.

Thanks for your comments Algi, appreciated. The first 2 for sure are dark and i'm begining to wonder if my monitor at home is too bright as they look really good when viewed on that and also strangely enough on a work colleagues iPad.
I must brush up on my P&P skills as these are straight from the camera, into Lightroom, B&W converted where I thought it worked better and exported as jpegs. So No 4 will gain from some work in that regard.
Your opinion on no 9 is spot on, it should not have made the cut.

The bands where very energetic and I would have been remiss not to capture some of that movement / energy I think, it is part of the story of the night

I like 1 a lot. The rest of them are okay, but pretty much what you'd expect from gig pics. But 1 is very unusual, and all the better for it. But then I'm a sucker for dimly lit shots.

Perhaps crop a little off the right?

cropped as requested

I like them all but REALLY (REALLY) like number 1 - if I were you I would have that as a canvas print on my wall.

Love it.
