David Perry Lindley (March 21, 1944 – March 3, 2023) was a multi-instrumentalist who founded the bands Kaleidoscope and El Rayo-X. The latter assembled in 1981 to support Lindey's debut album of the same name. That album included one of Lindsey's most commercially successful solo recordings: a cover of K.C. Douglas's "Mercury Blues." Despite his work as a solo artist and with the bands he formed, Lindsey is most recognized as a session musician, having worked with some of the biggest names in rock and country, including Jackson Browne, David Crosby, Graham Nash, Linda Ronstadt, Rod Stewart, Warren Zevon, Dolly Parton, Bob Dylan, and dozens of others. Lindsey played a wide range of instruments including the guitar, bass, banjo, violin/fiddle, steel guitar, zither, oud, charango, gumbus, cittern, bouzoui, cümbüş hardingfele, and bağlama to name just a few. He passed away on March 3, 2023 at the age of 78 after a long period of ill health.
