We went to see The Necks tonight at le poisson rouge. Great show - they played one song, and it was a hour long, so essentially they played the whole show without stopping. The music of this Australian trio is hard to describe - I'd say ambient avant-garde jazz is probably the closest. But their structures remind me of the post-rock bands (like Tortoise) that I like. They play repeating patterns that shift, progressions that build up to something resembling a crescendo and back. They were intense in concert, much more so than on their albums.
