Jack Johnson recorded his fourth album using nothing but solar power. This is somehow fitting for a singer-songwriter, surfer, and filmmaker who spends most of his days floating in the ocean under Hawaii's open skies. The forces of nature certainly seem to have found their way into the mellow grooves of standout tracks like "What You Thought You Need," "Adrift," and "Go On," songs so lovely and effortless that you can almost hear the melodies coming to Johnson on a warm breeze that rustles through the coconut trees. Sleep Through the Static documents his best work to date, even better than the Curious George soundtrack. The sedate singer transforms the acoustic campfire strums of the past into sublime, soulful ruminations on his wife, kids, and the state of the world. He even manages to conjure up some real anger on the title track, which is hardly diminished by its lavish grooves and glistening harmonies. --Aidin Vaziri
