The amount of talking was ridiculous, all the way through, even could be heard over the quieter bits of songs. I don't know if the lighting always has those bright white lights aimed to dazzle the audience (first NMA gig in 19 years) but that helped spoil the gig for me, and gave my better half a headache. I thought the sound could have been better too, Justin's vocals were too quiet, Justin's voice and lyrics are important and should be heard (Joolz' bit couldn't be heard either). The guitars also seemed to lack power,and the whole thing was too quiet.
Really enjoyed the performance despite not knowing a fair few tracks (the last album I bought was Strange Brotherhood)
