Stylistically the movie is a parody of rock documentaries, purportedly filmed and directed by the fictional Marty DiBergi (Rob Reiner). The faux documentary covers a 1982 United States concert tour for the fictional British rock group "Spinal Tap" to promote their new album Smell the Glove, but interspersed with one-on-one interviews with the members of the group and footage of the group from previous points in their career.
