David Perry Lindley (March 21, 1944 – March 3, 2023) was an American musician who founded the rock band El Rayo-X and worked with many other performers including Jackson Browne, Linda Ronstadt, Ry Cooder, Bonnie Raitt, Warren Zevon, Curtis Mayfield and Dolly Parton. He mastered such a wide variety of instruments that Acoustic Guitar magazine referred to him not as a multi-instrumentalist but instead as a “maxi-instrumentalist.” On stage, Lindley was known for wearing garishly colored polyester shirts with clashing pants, gaining the nickname the Prince of Polyester.

The majority of the instruments that Lindley played are string instruments, including violin, acoustic and electric guitar, upright and electric bass, banjo, mandolin, dobro, hardingfele, bouzouki, cittern, bağlama, gumbus, charango, cümbüş, oud and zither. He was the unparalleled master of the lap steel guitar in the rock music sphere, and an expert in Hawaiian-style slide guitar blues. Multi-instrumentalist Ben Harperacknowledges Lindley as an important influence.

Lindley was a founding member of the 1960s psychedelic band Kaleidoscope and worked as musical director for several touring artists. He occasionally scored and composed music for film.

David Perry Lindley was born in San Marino, California, to Margaret (née Wells) and John Lindley on March 21, 1944. When Lindley was growing up in Los Angeles, his father had an extensive collection of 78 rpm records that included Korean folk and Indian sitar music, as well as Spanish classical guitarists Andrés Segovia and Carlos Montoya.
