I too love this album, but I should say that I don't find them all too appealing live. I really don't feel like Lauren is cut out for performance at this point in time. I could be entirely off, but she seems pretty unsure of herself when on stage and whether to trust her in-ear monitor or not. That, and there is little to no stage presence at all between the three of them, but most so from her. I get that you can only do so much when in front of staged keys/sampling equipment, but come on! Anyhow, that's just my opinion. Don't stone me too hard. All things aside though, really catchy stuff. It's pretty apparent that the tracks not heard until this album were recorded much later than say The Mother We Share and Recover (I see you too Gun + Lies). Out of the new tracks, I didn't find myself skipping over any, but they don't seem to stand on their own in my eyes except for Night Sky and We Sink.
I'd save your 17€ and just stay in and watch this instead. I know it's nothing like actually being present and feeling that heavy bass reverberate inside your chest and getting out and moving, but you could maybe save the cover for another night with another act. I guess it also depends who they're playing with too.
I agree with you on their stage presence. When I saw them they seemed really shy and out of place. I think they just need some time to let everything soak in. They exploded pretty quickly.
