A summary of the new wave. "Parallel Lines" is one brilliant track after another. The opening 'Hanging on the Telephone' is itself a perfect example of the sound of new wave punk, juxtaposed with an energy that was unique to Deborah Harry and her band. The infamous 'One Way or Another' follows which faultlessly fuses a teeny-pop style with a hard punk sound (again something that was a fairly unique trait possessed by Harry), arguably the best on the album. At points, Blondie perform real head bangers: 'I Know But I Don't Know' and 'Will Anything Happen', through a more heavy metal sound: 'Fade Away and Radiate', soft rock: 'Picture This', through female cabaret: 'Pretty Baby' and 'Sunday Girl', and, like it or not, one of the best known number one singles ever: 'Heart of Glass', with that famous whiney tone of Harry's. All in all, the album not only highlights the diversity of Blondie as a band, but the diverse potential of new wave punk as a rock genre, and bands like the Jam and the Police serve only to support this. "Parallel Lines" is testimony to the fact that new wave punk was a great genre of rock that was fronted by bands that produced great albums. There is, of course, a current movement that is attempting to revive this era (Franz Ferdinand, Kaiser Chiefs etc).
