Essentials & Rarities (previously announced as Memories & Rarities) is a compilation album by Jean-Michel Jarre, released in 2011. The double CD set consists of two distinctive CDs: Essentials, which is a compilation of Jarre's most famous work, and Rarities, which compiles tracks made before his ground-breaking album Oxygène. [2] Despite his huge concert at Place de la Concorde and in China, which were a little less extravaganzas, the Jarre machine was in its first weapons in the scenic art. But no matter! But no matter! That is to Jarre's team that the management of the 150 years anniversary of the Texas state and also of the NASA's 25th birthday have given the pr3G.
