Off topic a bit:
The days of hiding a SLR in your boot or purse are gone when attending concerts, now that almost everyone carries a smartphone/camera. However, smartphones take pretty awful and indistinguishable images anyway, so why bother. I’ve stopped. Unless you’re a keener in the front row, the image quality is just not worth keeping or even sharing for that matter. If it’s about sharing an image on a social site, I would rather post a few complimentary words of praise about the artist rather than upload a crappy picture.

My advice: Take binoculars for the up close ‘memory’ shots. (Memory in your head, not memory in your phone) Not enough people take binoculars. By doing this and listening to the music, it will be more enjoyable with a sharper visual memory. It’s more effective, than trying to convince your smartphone to create Rolling Stone quality images.

And yes, I walked out of the Gordon Lightfoot concert. Different reason and topic. ;-P
