Purely on its merit, this is an amazing live album. The output is far more loud and ferocious than their studio performances generally were. As a big FotN fan though, I'm not sure that's always a good thing. Rather the live album is a perfect compliment to the studio albums, it is not meant to be a replacement unless you are a metal fan in which case you may like this better. What is impossible to replicate live is the dreamy, ethereal nature of the studio recordings. The best moment is the perfect version of "Dawnrazor" - this is how this song was meant to sound and is far superior to the album version. In most other cases, I think the versions are merely different and I appreciate them for that.
A must-have for fans, and a great starting point for new fans who will likely find this more accessible (at least at first) than the studio albums. I know that's an odd thing to say, but for FotN it may be true since EI is more straightforward kickin' rock and far less complex than an album like Elizium.
