As heartbreaking as it was to see Sonic Youth break up, the dissolution of that band has allowed its members to pursue other interesting projects. Body/Head, featuring SY's Kim Gordon and experimental guitarist Bill Nace, is the most avant-garde of those projects, eschewing the more pop-oriented side of Gordon's former band for the more outre—this is the Gordon of "Hallowe'en," not "Kool Thing." Nace's guitar builds a steady drone while Gordon moans in a seeming trance state before Nace's guitar spurts a continuing series of bent notes and Gordon howls like a cat in "The Eyes, the Mouth." "Actress" at first sounds like a lost radio transmission but grows into a beautifully dark beat poem of sorts that grows more haunting on each listen. Body/Head's improvisational wanderings aren't for everyone, that's for sure. Then again, those who've followed Gordon's work know she was always been at the forefront of SY's efforts to break convention, in tonality and song structure. With Nace's grounded drone-guitar work on hand, she pushes things further than she's ever gone on Coming Apart.
