I reckon that this band had done a run through of the likes of CSIT and Alex many moons ago, to check the feasibility of this tour. Theres no way that they decided on this tour and the 5/5 split without first playing through the SiT songs. So 2 weeks in Split was not the only rehearsal that was done, no way.
I've not read the last 10 pages or so but if people are giving out about the first night performance of a difficult set list then you need to check yo'selves, bitches. To rehearse too much can kill the vibe. Better to work it out on the road in an energised environment. I personally don't feel ripped off if I see a band and they fuck something up. I even love to see the interaction between band members when something goes wrong, the glances, the facial expressions of the humans that are doing difficult shit for my entertainment.
I'm not excusing sloppiness or a lack of care but you can rehearse all you want, nothing replicates performing in front of a crowd.
