The Crystal Method

Long accustomed to a crowded studio, the Crystal Method put their Rolodex to the test on their fourth album. Members of Metric, She Wants Revenge and LMFAO all appear, while New Order's Peter Hook lends his trademark bass to "Dirty Thirty" and Hasidic rapper Matisyahu takes an unlikely turn on lead single "Drown in the Now." The guests seem to have inspired the duo, who come up with an appealingly unpredictable set running from dubby, bhangra-infused downtempo through grinding electro-house and breakbeat-ridden modern rock, all of it sized to stadium proportions.
