Nina Hagen is a unique vocalist, ranging from a coloratura soprano to a guttural alto and phrasing in surprising, dramatically changing ways, so that her performances are musical roller coasters, full of sudden shifts in mood and volume. Singing alternately in German and English, Hagen is backed by rock tracks leaning toward punk on some songs, and by producer Giorgio Moroder's signature Euro-disco synth-dance sounds on others on this 14-track, 74-minute compilation. Want to hear a German-language version of the Tubes' "White Punks on Dope"? How about a performance of "My Way" (also in German) that rivals Sid Vicious' for outrageousness? Ultimately, Nina Hagen may be a period novelty act of the early '80s, a mixture of Toni Basil, Falco, and a hyena. But she gets your attention.
