"Walking on a Rainbow" is the debut album by Blue System, released in 1987. Blue System was a German pop group created by Dieter Bohlen after the breakup of Modern Talking, another very popular German duo. Bohlen continued to explore similar pop and Euro disco themes with Blue System that he had been known for with Modern Talking. The album "Walking on a Rainbow" includes tracks like "Sorry Little Sarah" and "Big Boys Don't Cry," which are reflective of the Euro disco and synth-pop style popular in the late 1980s. The sound is characterized by catchy melodies, danceable beats, and lush synthesizer arrangements, all hallmarks of Bohlen's production style.
