Logos Live is the fourth live album and eighteenth overall by Tangerine Dream and was released in December 1982. It is a live album from the concert at the Dominion Theatre in London, England. Much like Tangram with short movements connected by atmospheric segues, Logos captured a period of Tangerine Dream's evolution from experimental to melodic, documented also by their soundtrack to the motion picture Risky Business a year later.
From the two-hour concert, 50 minutes of music original to the concert was included on the album. The entire concert is included on the Tangerine Tree release Tangerine Leaves Volume 1: London 1982. The same concert was played at Fairfield Halls in Croydon on 31 October 1982 and released in a superior quality as Tangerine Tree Volume 12: Croydon 1982.
The releases of Logos Live do not split parts one and two, but these thematic sections have been remixed or re-recorded and used in other albums as separate tracks. Some CD releases combine parts one and two into a single track.
