Guitarists and artist who cares

There's no doubt that Chinese artist Zheng Wei, 33, is a die-hard fan of rock 'n' roll. He's engraved images of his favorite guitarists - as many as 185 of them - onto a nearly 6-meter-high wood block to show respect for his idols.

The Tree, the highlight of Zheng's ongoing solo show at Beijing Art Now Gallery, is a documentary of guitarists born from the 1890s to the 1970s, featuring influential figures in blues, rock 'n' roll, jazz and country music. Faces of musicians appear like fruits on a "guitar tree" stringed with wires.

"It's what I know about the guitarists in the rock 'n' roll world," says Zheng, noting that while many are household names, others who exerted great influence have been largely forgotten.
