Led Zeppelin's May 11, 1969, performance at the Green Lake Aqua Theatre -- which had a 5,000-person-capacity grandstand -- also drew fans who watched from rowboats. They played between opener Translove Airlines and headliner Three Dog Night. Follow this link to see photos from the Green Lake show.
The concert was nearly five months after the band's first, unadvertised concert at the Seattle Center Arena opening for Vanilla Fudge. Later in 1969, they played the Seattle Pop Festival in Woodinville and packed more than 62,000 fans into the Kingdome on July 17, 1977. Watch the full Kingdome show below.
