Hm, let's see. I went to Berlin last fall and saw Weyes Blood (great), I saw this funueral doom band called Bell Witch a while back (they're songs are like 80 min so they usually play one song). Then I was over at the O2 in London a few months back to see John Mayer (always brilliant live). Next month there is Massive Attack, Chelsea Wolfe and Tool and I will try and see Dinosaur Jr as well.
Anyway, live music is as much about atmosphere and energy from the crowd as anything, and in regards to that this was unmatched. I've been to hip hop shows where I've disliked or not known about the artist/group and had incredible times because the energy from the crowd lifts the entire experience.
