The electronic music group Tangerine Dream has released more than three hundred albums, singles, EPs and compilations since the group was formed in 1967. Eras Tangerine Dream's releases have been divided into several eras based on the record label of the time. Tangerine Dream's first releases were on the Ohr label. The Ohr logo was a pink ear, thus fans refer to this era as the Pink Years; this covers Electronic Meditation (1970) to Atem (1973). In 1974, the band switched to Virgin Records with the release of Phaedra, thus the Virgin Years. The switch to the Jive Records label with their blue logo was the start of the Blue Years beginning with Poland in 1984. The Melrose Years started when Tangerine Dream switched to Peter Baumann's Private Music label, located on Melrose Avenue in Los Angeles; the first release was Optical Race (1988). This was a period of rapid line-up changes, beginning with the departure of Christopher Franke, and ending with the departure of Paul Haslinger and the introduction of Jerome Froese and Linda Spa. A switch to the Miramar label in Seattle gave the name Seattle Years with the release of Rockoon (1992). Tangerine Dream moved to the Castle label in 1996 briefly before Edgar Froese created his own TDI label, thus this era is the TDI Years or sometimes the Millennium Years. In late 2005 the label was renamed Eastgate, giving rise to the Eastgate Years. In late 2014 Edgar Froese conceived of translating the current knowledge of quantum mechanics into sound, thus the Quantum Years and the release of Mala Kunia. Series The Dream Mixes series is a project initiated by Jerome Froese. The series has a dance music slant and primarily consists of remixes of other TD material. The Dante Trilogy is a musical interpretation of Dante's Divine Comedy. The Five Atomic Seasons series was commissioned by a Japanese businessman who survived the atomic bombings of both Nagasaki and Hiroshima. The Bootleg Box sets, the Bootmoon series and the Vault series are live concerts sourced from recordings; many were first released as part of the Tangerine Tree project.
