Pergamon (1986), originally released as Quichotte (1980), is an album of electronic music released by Tangerine Dream. It is a selection from the two live concerts held on 31 January 1980 at the Palast der Republik in East Berlin. The second of the two original concerts is available as Tangerine Tree Volume 17: East Berlin 1980. The original title Quichotte is a reference to Don Quixote, a film version of which was being screened in a nearby cinema as one of the concerts was performed, while the retitle is a reference to the Pergamon Museum located in East Berlin near the Palast der Republik.
Remixed excerpts from "Quichotte, Part One" were used in the soundtrack for Wavelength. The piano solo from Part One has been released on other albums as "Pergamon (Piano Part)" and re-recorded as "Pergamon Sphere".
