David Perry Lindley (born March 21, 1944) is an US-American musician who founded the band El Rayo-X, and who has worked with many other performers including Jackson Browne, Warren Zevon, Curtis Mayfield and Dolly Parton. He has mastered such a wide variety of instruments that Acoustic Guitar magazine referred to Lindley not as a multi-instrumentalist, but instead as a “maxi-instrumentalist.” The majority of the instruments that Lindley plays are string instruments, including the acoustic and electric guitar, upright and electric bass, banjo, lap steel guitar, mandolin, hardingfele, bouzouki, cittern, bağlama, gumbus, charango, cümbüş, oud, and zither. Lindley was a founding member of the 1960s band Kaleidoscope, and has worked as musical director for several touring artists. In addition, he has occasionally scored and composed music for film.

As a teenager, Lindley took to playing the banjo and the fiddle. By his late teens, he was acknowledged as an award-winning player, having won the Topanga Banjo•Fiddle Contest five times. From 1966 to 1970, Lindley was a founding member of the all-styles psychedelic band Kaleidoscopewhich released four albums on Epic Records during that period.

After Kaleidoscope broke up, he went to England and played in Terry Reid‘s band for a couple years. In 1972, he teamed up with Jackson Browne, and played in his band through 1980. During the 1970s, he also toured as a member of the bands of Crosby–Nash, Linda Ronstadt and James Taylor.

In 1981, Lindley formed his own band, El Rayo-X. Jackson Browne produced their first album. Their last show before breaking up was December 31, 1989. Since that time, he has toured as a solo artist, and as half of a duo, first with Hani Naser, then with Wally Ingram. He also played on a multitude of studio sessions. Between his work in the studio as a session musician or on tour as a sideman or bandleader, Lindley has worked on learning new instruments. He is famous for having written the only song glorifying (a brand of) condoms, “Ram-a-Lamb-a-Man,” from his album “Win this Record!
