Volta brings back some of the electronic beats and rough passion from Vespertine and Homogenic, but it also incorporates some (thankfully, much less) of the vocal beats and sounds Björk used in 2004’s Medulla. A noticeable addition is the voice of Antony and the Johnson’s singer Antony Hegarty, who joins Björk on two tracks. The lyrical play between the two takes the formal duet style found on Selmasongs and makes it more Björk-esque, with Hegarty’s eclectic voice meshing well with Björk’s own distinctive sound. Politics come into play on “Declare Independence,” with a drumbeat fit for marching in the background. The whole album comes together with the unique beats of Timbaland. Another Björk masterpiece.
