Systems in Blue is a German pop band originally composed of Rolf Köhler, Michael Scholz, and Detlef Wiedeke.

The original band members started in the beginning of the 1960s, working in different bands during 1960s and 1970s, Köhler worked for several different artists such as Blonker, Uriah Heep, Blind Guardian, Helloween, Grave Digger, Gamma Ray, Iron Savior, Savage Circus, Tokyo, Mephistopheles, and Kin Ping Meh (featuring Geff Harrison) among others.

They were part of the choruses of the Dieter Bohlen produced Modern Talking in 1984–1987 and 1998–2000 and Blue System in 1987–1997 with Köhler as the refrain singer.

After a pause, Systems in Blue started again with Michael Scholz, Detlef Wiedeke and a new member Olaf Senkbeil who was a close friend and yet working with them on several projects.

This album charted in more than ten countries in digital and had very nice results with the first single "Play for Me the Melody of Love" including remixes from Captain Trash and MS Project.
