Since embarking on her journey as a solo artist, Björk has made an art out of stripping traditional musical elements from her recordings. With "Medúlla," her seventh studio album, she has created her most reduced recording yet. Except for a piano here and a synth bass there, all of the sounds were concocted by sampling and manipulating the human voice. The exuberant "Who Is It (Carry My Joy on the Left, Carry My Pain on the Right)" finds Björk working with Inuit throat-singer Tanya Tagaq and human beatboxer/ ex-Roots member Rahzel. The oh-so-quiet "Sonnets/ Unrealities XI" and the beautifully lopsided "Desired Constellation" spotlight the Icelandic Choir. To be sure, "Medúlla" is a demanding recording that asks a lot of its listeners. But those who are up for the challenge will find much to admire. In Björk's world, voices carry.—MP
