JD Souther, Who Wrote Hits for the Eagles, Dies at 78

JD Souther, who crafted many of the biggest hits to come out of the Southern California country-rock scene of the 1970s, including for the Eagles, Linda Ronstadt and James Taylor, and who later played a wizened music industry veteran — in other words, a version of himself — on the hit television show “Nashville,” died on Tuesday at his home in Sandia Park, N.M., in the hills east of Albuquerque. He was 78.

His death was announced on his website. A cause was not provided.

Beginning in the late 1960s, Mr. Souther was part of a coterie of musicians around Los Angeles who found themselves circling the same sort of peaceful, easy, country-inflected rock sound. They played at the same venues — among them the Troubadour, the famous West Hollywood nightclub — and lived and partied in the same canyons in the Hollywood Hills.

Mr. Souther played with or wrote for most of them. Though he was brought up on jazz and classical music, he easily mastered the country-rock vernacular on songs like “Faithless Love” and “White Rhythm and Blues,” for Ms. Ronstadt; “The Heart of the Matter,” which he wrote with Don Henley; and “Her Town Too,” a collaboration with Mr. Taylor that they sang as a duet.

He also played a central role in the formation of the Eagles, encouraging Ms. Ronstadt, his girlfriend at the time, to hire his friend Glenn Frey as part of her backup band. After Mr. Henley joined, he and Mr. Frey decided to form their own group, along with two other members of Ms. Ronstadt’s ensemble, Bernie Leadon and Randy Meisner.

Mr. Souther was almost the fifth Eagle: He joined the quartet for an afternoon tryout at the Troubadour, but he decided that the band was already perfect, and that he’d rather write for them.
