JOE HENRY Fuse (Mammoth) Rating: 5 out of 7 By Chris Morris Singer-songwriter Joe Henry has undergone quite a metamorphosis over the years: originally a roots-oriented performer, he has pursued his muse into stranger quarters of late, and now specializes in a skewed, unsettling variety of pop music. On his first album since the excellent Trampoline three years ago, he continues on his own path. This self-produced effort, with a mixing hand from T-Bone Burnett and Daniel Lanois, enters off-kilter lyrical territory on jarring numbers like "Monkey" and "Skin And Teeth," which hint at dark secrets lurking behind the door; Henry also offers occasional, disquieting samples, an instrumental dedicated to the intransigent baseball player Curt Flood, and wraps things up with a nod to the Byrds and Dr. Strangelove with a straight-faced reading of the music-hall standard "We'll Meet Again." Henry remains an altogether too-well-kept secret; in his unassuming way, he treads untrammeled pop ground to great effect.
