10 Grammy Greats: The 2012 Nominees Making Waves in the Industry

Decades before Taylor Swift conquered the country and pop worlds, Campbell reigned over both. Just look back to the 1968 Grammy Awards: Campbell captured four trophies, including best country and Western male solo vocal performance for "Gentle on My Mind" and pop vocal performance for "By the Time I Get to Phoenix." Renowned for his supple voice and sterling guitar playing, Campbell, who has been married to wife Kim for 30 years, will receive the lifetime achievement award at the 2012 Grammys, commemorating his 50-plus years in show business, including as a member of the historic studio musicians collective dubbed The Wrecking Crew. The 75-year-old, whose life is being developed into a biopic by Walk the Line's producers, will perform on the Feb. 12 awards show, accompanied by The Band Perry and Blake Shelton. Although recently diagnosed with Alzheimer's, Campbell has extended his farewell tour into June and says playing continues to give him great joy, especially since three of his eight children have joined his band. "I love that I've got my kids there with me," he says. "They can really flat-out play." He also loves performing "all the Jimmy Webb things," he says, bursting into the Webb classic "Wichita Lineman," a top-5 pop hit for Campbell in 1968. "I like 'me, I' songs -- 'I feel, I think, I need, I want,' " he says. "That's what grabs a person."
