Over the course of the next three decades, Dylan continued to reinvent himself. Following a near-fatal motorcycle accident in July 1966, Dylan spent almost a year recovering in seclusion. His next two albums, "John Wesley Harding" (1968) including "All Along the Watchtower," later recorded by guitar great Jimi Hendrix—and the unabashedly countryish "Nashville Skyline" (1969) were far more mellow than his earlier works. Critics blasted the two-record set "Self-Portrait" (1970). "Tarantula," a long-awaited collection of writings Dylan published in 1971, also met with a poor reception. In 1973, Dylan appeared in "Pat Garrett and Billy the Kid", a feature film directed by Sam Peckinpah. He also wrote the film's soundtrack, which became a hit and included the now-classic song "Knockin' on Heaven's Door."
