Beginning in the 1980s, Dylan began touring full-time, sometimes with fellow legends Tom Petty and the Heartbreakers and the Grateful Dead. Notable albums during this period included "Infidels" (1983); the five-disc retrospective "Biograph" (1985); "Knocked Out Loaded" (1986); and "Oh Merc"y (1989), which became his best-received album in years. He recorded two albums with the all-star band the Traveling Wilburys, also featuring George Harrison, the late Roy Orbison, Tom Petty, and Jeff Lynne. In 1994, Dylan returned to his folk roots, winning the Grammy Award for Best Traditional Folk Album for "World Gone Wrong."
