David Perry Lindley 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.
