Not sure the cell phone videos are doing it justice really. It's rare that they ever do. Although having not been there or heard any recordings yet, it's hard to tell really. Given the surprise nature of the shows & the extraordinary setlist, I guess it'll be a while before any recordings make it out of the trade pool.
I think they sound ok even on these poor quality clips that are available so far. I can think of a few of their contemporaries that sound way worse these days. Bauhaus was indeed a very long time ago but I think the occasional nostalgia show is ok and they seem to get the balance right. And the setlist looks pretty cool.
