Swedish reedsman Mats Gustafsson has written five Hidros works, the other four having been interpreted by the NU-Ensemble and the Copenhagen Arts Ensemble. This third incarnation was specially prepared for an augmented Sonic Youth, featuring (amongst others) guitarist Loren Mazzacane Connors.
The piece was recorded live at its premiere in 2000. The players were housed in small rooms of the Art museum in Ystad, Sweden, during its KulturBro festival. Jim O'Rourke was in charge of the mixing, the only performer capable of filtering the composite whole. The audience were free to wander from chamber to chamber, experiencing various subjective perspectives of the performance.
