2. The Big Sleep in Search of Hades
3. 3 AM at the Border of the Marsh from Okefenokee
4. Invisible Limits
Consisting of four parts, Stratosphere reworked the Tangerine Dream trademark sound--a heady mix of electric guitar, drum, and assorted other electronic instruments--into a form more readily available to those new to the genre than their previous works. A rich blend of racing sequences, dramatic chord structures, and a stranger-than-strange bluesy treatment of a track called "3 am at the Border of the Marsh from...." A surreal experience indeed. This was the last Tangerine Dream release to feature long time associate Peter Baumann, who left the band a year later.
