Terminal 5 remains one of the worst venues in the city. The bar apparently no longer allows you to keep the lid on your drink so that's a downside. Also, there are always sound problems there, but they were minimal this time, restricted mostly to the opening act and Nutini's back-up singer.
Otherwise, the show was pretty solid, but Nutini is not the most interesting performer I've ever seen. He's not great at transitioning between songs, staying awkwardly silent most of the time, and the show was oddly paced. He would often build energy with a few wonderfully performed songs the Jenny Don't Be Hasty/New Shoes medley of the first album and then let play a much slower song that let all that energy deflate. This happened quite often and made the show a little exhausting. He does, however, sound fantastic live and when the energy is up, there's nothing like it. The performance of "Iron Sky" was a highpoint. Definitely recommend seeing him live, but perhaps at a venue where you're allowed to sit every once in a while and react to the mood Nutini is currently setting.
