Radio is the ninth album of the German a cappella group Wise Guys. It is built in the form of a radio broadcast: between each individual piece come jingles and other small tidbits, such as the news or sports. This stands as the first concept album of the Wise Guys. The CD ranked #3 in the German album charts and stood for fifteen weeks in the top 100 of the charts. Like its predecessor Wo der Pfeffer wächst, the CD is purely a cappella with no instrumentation and, with the sole exception of the "Mad World" cover, is entirely self-composed numbers. The majority of the songs were composed by Daniel Dickopf.
