You can tell from the title of this album that it's either a spoof project or the work of a band with severe self-esteem problems, but The Lonely Island certainly aren't lacking in the latter department. Akiva Schaffer, Andy Samberg and Jorma Taccone - aka 'The Dudes' - met in high school and have made a success out of their enduring schoolboy immaturity by creating this fictional rap group, initiated via skits on legendary variety show Saturday Night Live.

It might sound like an obvious statement, but 'Incredibad' should certainly not be judged as a musical project: it's a collection of musical parodies, mostly rap songs, that occasionally provoke involuntary titters but rarely belly-laughs. Whether they're rapping about a new brand of champagne bearing Carlos Santana's name ('Santana DVX'), their love of sports ('We Like Sportz'), or defining the rules of a proposed 'Space Olympics' event, The Lonely Island thrive on adolescent humour - i.e. there's nothing clever or sharp about these lyrics.

Undeniably, though, the trio possess brilliant comic timing and are well aware of the juvenility of their songs - many of which highlight how ridiculous and meaningless modern music is. They're also apparently in possession of some of the most impressive persuasion skills in Hollywood; hearing a host of big stars guest here (hearing Justin Timberlake, T-Pain, Norah Jones, Julian Casablancas and the repugnant Jack Black) all take temporary leave of their senses is truly bewildering.

It's purposely bad music and may raise a smirk every now and again (hearing Natalie Portman psychopathically rant "Put my foot down your throat till your shit's in my shoe" - is peculiarly amusing), but 'Incredibad' is most likely to appeal to the teenage boy in your life. If that doesn't say it all, then nothing will.
