By the time of 1998's "Super Go!!!!!" EP and full-length "Super æ", the band started to break sharply from their earlier atonal noise rock/Japanoise sound by introducing many elements of sweeping electronica effects and thoroughly constructed psychedelic rock jams into their music. Perceived analogies with the music of Can became common during this period. Described as "tumultuous space-sludge", "Super æ" has most often been compared to the defining elements of 1970s krautrock. Soon after its initial release in Japan, "Super æ" was met with a considerable amount of acclaim from the international music press, recognized as a modern-day avant-garde artifact and progressive "masterpiece". Notably, "Super æ" was considered one of the best albums of the 1990s by Pitchfork Media.
