Images taken on Planned location

After attending the gig, I was able to take many photos of them in action, for example, the guitarists, their instruments and the lead singers. I am hoping that out of the many photos I took, I will be able to find one to suit my magazine front cover. I am not entirely happy with the setting of my photos, however I will be able to edit these photos heavily using Adobe Photoshop, to create a suitable front cover image. The quality of the photos as they stand isn't as good as I would initially like, however I am able to also edit this. 
After sorting through the 50 images I took, the photos below are possible images I could use:

I think that this first image has the most potential for a front cover image, as there is a lot happening in the picture and creates that 'band' atmosphere. The poses are confident and show musicality and I think that if I crop and edit the lighting of this photo, I could use it as a potential image for my front cover.

The second image isn't ideally positioned, however I could use the lasoo tool on photoshop to cut out the guitarist and place it onto a more neutral background, which could look effective with some experimentations.

This third image is similar to the second, however shows different poses and could also be potentially edited and used.
