The Pop Idol phenomenon has been responsible for some truly terrible crimes against music. But surely none quite as horrifying as G4, the X Factor runners-up who (tragically) refuse to let defeat stop them from launching a recording career. The vocal quartet take their name from the fact that they all studied at the Guildhall School of Music, which just goes to prove that technical training is no substitute for taste. On this excruciating debut album, pop and classical standards such as Life on Mars, Bohemian Rhapsody and Nessum Dorma are not just murdered, they're taken down to a cellar, clinically dismembered and stuffed into body bags. The only redeeming feature is that they send you scurrying back to the originals, just so that you can get the bad taste out of your mouth. Of course, G4 may not have realised the sheer awfulness of what they're doing - but frankly, that's not much of a defence.
