L7's sixth studio album, "Slap-Happy", was released on the band's own label Wax Tadpole Records in 1999. To promote the record, on July 17, 1999, L7 had a plane fly over the crowd at the Lilith Fair at the Rose Bowl in Pasadena, California, with a banner that read, "Bored? Tired? Try L7." The following day, an airplane towed a banner over the crowd at the Warped Tour at the Stone Pony lot in Asbury Park, New Jersey. The banner read "Warped needs more beaver...love, L7." Greenwood later left the band and was replaced by Janis Tanaka, formerly of the San Francisco band, Stone Fox.
