In June 1999, Tangerine Dream performed a one-off concert during the Klangart Festival in Osnabrück in Northern Germany, presenting the then brand-new album Mars Polaris. The complete album was performed, though the track order differs from that on the album. The music performed is essentially identical to the studio versions, with some additional guitar and percussion work. Some older compositions were included in the main set and the encores (which are unfortunately missing on this album release).
Copies sold in the UK have been found with an additional barcode sticker showing the TDP number listed below.
In March 2009 the album was re-released with different cover design as part of an extensive digipack series (consisting of a total of more than 60 CD and DVD releases) by the Germany based Membran record label.
