By recording in churches and experimenting with different sounds, alternative rock band Coldplay prove they're not afraid to think outside the box and push for greater achievements. Lead vocalist Chris Martin has described the band's first three albums as a 'trilogy', and UK and US No 1 single Viva la Vida as a step in a new direction. The track focuses more on acoustic guitar and sustained bass than any of their previous material. This adds a new sound to the band's repertoire - you can definitely hear classical influences in the song. With an inspiring message of living life to the full, this song is perfect for easy listening and perfectly portrays Coldplay's unique sound. Lost! is about as close as a band can get to a Leona Lewis-style declaration of love, with Martin utilising the resonating lower register of his voice to great effect. Lovers in Japan/Reign of Love is a pleasantly mellow track with a haunting, sustained choral line laced with a laidback, hippie vibe. One of the standouts is Strawberry Swing, a country-flavoured, folksy tune reminiscent of summer picnics, or nights under the stars. It's possible Coldplay have outdone themselves here, taking a brave leap into a new artistic direction that few bands dare.
