modern guilt' is the tenth beck album but first for his new label xl and the first with danger mouse on production. beck and danger mouse knew each other casually before making the record - some of beck's former musicians ended up playing with gnarls barkley - but they were both surprised at how naturally they worked together. the album is full of off-kilter rhythms and left-field breakdowns, with an overall 1960s british vibe. beck's vocals float over the music as if he's singing along to some mystical radio station in the next room. the title track has the groove of a good zombies single, while the twangy guitar and uptempo beat of 'beggars shoes' make it sound like beck's cruising at maximum speed down route 66. cat power's chan marshall added backing vocals to a few tracks, including the melancholy 'walls'.
