AndyH,
Sorry to set this one running! Yup enjoyed the gig, lots of energy, extremely tight and good sound (and not just saying that because you're here....oh no). Felt like a slightly short set but I put this down to them being a young band with only one album of material that the audience would know, and actually I think a shorter set filled with the known songs is a better bet than a longer one with lots of new stuff. Certainly at this stage and at that venue.
The tuning thing only bugged me as it's something I don't do, and don't like to hear. It's not a major problem but did detract a tiny bit for me. I sort of take on board what you say about the singer stepping on a pedal as he does bound around a lot. I did wonder if it really was a tuning thing or just something he does in the spaces between the songs as he wasn't tuning, just sort of checking.
