It was a short lived stint...Jimmy toured with them in 2000

By Your Side, produced by former Aerosmith collaborator Kevin Shirley, hit record stores in January 1999. Later the same year, the Black Crowes teamed up with former Led Zepplin guitarist Jimmy Page for a series of concerts in the U.K. and the U.S. In 2000, Jimmy Page and the Black Crowes Live at the Greek, an album consisting mainly of Zepplin standards, ruffled some feathers in the retail world because of its exclusive online distribution through Musicmaker.com.
