Anla Courtis & Lasse Marhaug - North and South Neutrino (2004)

The first collaboration between Norwegian noisemaker Lasse Marhaug (of Jazzkammer, etc.) and Argentinian Anla Courtis (of Reynols, as well as the hilariously named L'Autopsie A Révélé Que La Mort Était Due À L'Autopsie) was started as early as 1997, but wasn't finished until 2003. I don't know how intensely they have worked on it in the years between, but this is one finely crafted jewel of noisy musique concrète. Slowly developing extreme frequencies are joined by deep drones and blistering feedback: not a surprising fusion of elements, but when it's done as well as this, and builds so beautifully to its climax, there's no point in arguing.
'North and South Neutrino' was released in January 2004 on a great little Greek label called Antifrost, in a limited edition of 500 copies. The nice artwork is by Leif Elggren, by the way. This duo later did a tape release entitled 'Jordslev Hojaldre' (Quasi Pop, 2007), which I haven't heard yet. They have also released hundreds (probably) of other things, each, in all sorts of combinations, but of what I have heard of the rest of their respective output, nothing comes close to this.
