As a title, Bilingual is a double-edged sword. Disregard its sexual connotations and concentrate on its musical implications -- Bilingual is a rich, diverse album that delves deeply into Latin rhythms. It's not a crass, simplistic fusion, where the polyphonic rhythms are simply grafted over synthesizers and a disco pulse. Instead, Bilingual is an enormously subtle album, with shifting rhythms and graceful, understated melodies. The music isn't the only thing subtle about the album -- Neil Tennant's voice and lyrics are nuanced, suggesting more than they actually say. Furthermore, Bilingual consists of the most optimistic, happy set of songs the Pet Shop Boys have ever recorded. Whether it's the smooth disco of "Before" or the insistent rhythms of "Se a Vida E," Bilingual is filled with joyous, if subdued, sounds. If anything, it's further proof that even if the Pet Shop Boys aren't gracing the top of the charts as frequently as they did during the late '80s, they are crafting albums that are more adventurous and successful than they did when they were one of the top singles acts in pop music.
