I was there, at the live performance in Sonar Festival, Barcelona. It was unforgetable, one of the most haunting musical performances/shows I have ever witnessed. At one point we were handed small shiny plastic disks to stick on our foreheads, and as a strong strong light walked on the audience, you could see the reflections from the discs like rays coming out people's heads, perfectly traced by the smoke - brilliant!:).
The music was right, the place was right, the mood was right... thick layers of electronic sounds, slowly changing and pulsating over time, episodes of percussive madness, powerful bass. This is music to be experienced, not to listen to in your sofa at home.
