Established in 2004 in Stavanger, Norway, Ultralyd is a Norwegian jazz/free rock band initiated by the legendary sax player Frode Gjerstad. Gjerstad left after their second album ”Chromosome Gun” (Load Records) to be replaced by Møster. During two extensive European tours and several studio sessions Ultralyd's direction has gradually changed from a rather chaotic free rock approach towards composition and more structured forms of improvisation, experimenting with different layers and altered roles of the instruments, integrating elements from contemporary and electronic music, funk and doom metal and ending up with an album that might be classified as something akin to the improvised chamber rock King Crimson were doing around 1973.
