Aside from Wire's John Peel sessions, this is Wire's only release that includes a large amount of unique content. The latest live albums (On The Box, etc.) are really more what you would expect from such a release: more aggressive performance to accommodate the missing use of live electronic instrumentation, poorer sound quality, and so on. Well, the live performances on D&E are no exception to poor sound quality, but this time Wire keep a fair amount of electronic influence in their work; not just guitars and percussion here, which makes this all the more valuable in my opinion. This release, to me, is more suited to be considered the 4th Wire album over Newman's A-Z (for one Newman wrote nearly all the tracks on that album on his own, so why would they be referred to as Wire songs?)
I also don't understand what some people consider to be issues with this release. You do hear a lot of experimental work, which I love, and if you're a Wire fan so should you, but there are also a great deal of more conventional songs, like 'Go Ahead' and 'Relationship'. Basically, you get to hear at least a dozen tracks that haven't been recorded in the studio (some of these tracks were re-recorded by Newman for solo work, and I know that 'Underwater Experiences' was an earlier demo). One thing I don't get is why 'Heartbeat' is just thrown in with the mix, as it was from a different performance altogether; just doesn't fit well, despite its being a good track.
I don't want to spoil the atmosphere of the album by explaining much of the music, but I will comment that it crosses between more aggressive Chairs Missing-era and something not quite Wire (mainly because without having come from the studio it's hard to picture what the final production qualities would be like).
And yes the final two tracks are from their Our Swimmer EP (can't really call it a single because it wasn't promoting anything, it just was). These two tracks are quite different from what you hear on E&D, and for that matter, Wire's other albums. I would've really enjoyed getting to hear more than just these two songs from this new style that they developed.
But this album is still valuable even for people who aren't fans of live recordings (a lot of time the audience is just too noisy and compromises the music, but in this case the audience was so baffled by what they heard you really don't hear much of them.) I did take one star off because it isn't perfect, but still great.
