Photographer Herb Greene had barely heard of Led Zeppelin when they came into his San Francisco studio in the first weeks of 1969 for a photo shoot. The group's debut album hit shelves that same month and they were in the midst of their inaugural American tour, opening up for Country Joe and the Fish during a four night stand at the Fillmore West. "I knew about the Yardbirds," he says. "I knew nothing about this new band with Jimmy Page. But they booked a session because they wanted some 8-by-10 glossies, as they used to say in the trade." Greene estimates he spent less than an hour with the band, but during that time he snapped off an incredible series of photos of Zeppelin that have been rarely seen until now. This is Zeppelin before the tight pants, the private jet and the swarms of mad groupies. Click here for more information.
