Museo Rosenbach are one of a number of Italian progressive bands of the 70s known for a single album, in their case the highly regarded Zarathustra (1973). The band formed in Sanremo around 1971 from members of Il Sistema and a cover band called La quinta strada. The band broke up shortly after the release of their album, but numerous other recordings have surfaced since, including a 1972 live album. In 2000, two of the original members released a new album under the old name with new players. Zarathustra remains one of the highest ranked Italian albums of all time on the Gnosis site.
