There are two artists that go by the name of Prosper: 1. PROSPER was born in Bottrop, a town situated in the northwestern part of the german Ruhrgebiet which is dominated by an eponymous coal mine. The band's story began 1973 as PROSPER I with heavy line-up changes. Jürgen Pluta (keys) was a co-founder but soon went to WALLENSTEIN to play the bass. Evert Brettschneider (guitar) and Matthias Geisen (bass) were early members to form a constant line-up and to reduce the name to PROSPER. They were later followed by Friedhelm Misiejuk (drums, percussion), Fritz A.
