With the release of a new retrospective box set from Tangerine Dream approaching next month, a previously unreleased track from the group - titled 'Act 2: Baroque' - has been shared online. You can check it out above.

The track features in the box set as part of the Oedipus Tyrannus soundtrack, which dates back to July 1974.

The box set, which is titled In Search Of Hades: The Virgin Recordings 1973 - 1979, features remastered versions of the albums Phaedra, Rubycon, Ricochet, Stratosfear, Encore, Cyclone and Force Majeure. All the records have been remastered from their original first-generation tapes for the box set.

The release will be available in an 18-disc ultra deluxe edition and a seven-disc standard edition. It's out on June 14 and can be pre-ordered here.
