FOR anyone familiar with the general vibe of Jack Johnson, the world's best-known surfer turned filmmaker turned singer-songwriter turned green activist, it probably wouldn't be hard to picture his home here on the North Shore. Near the porch of his modest house is a thriving patch of taro, the versatile plant found in native Hawaiian cuisine. The roof of an adjacent building is tiled with solar panels, glinting in peak sunlight. And as he kept one eye trained on the movements of his two sons, the older of whom is nearly 4, Mr. Johnson sat at a picnic table in a T-shirt and board shorts.
"I know it's mellow to the point of annoyance, to a lot of people," he said, regarding both his hang-loose image and his brand of upbeat acoustic pop. "But it is truly who I am."
