Robert Plant and jazz violinist Jean-Luc Ponty will join Nigel Kennedy for a one-off concert at the Royal Albert Hall next month.
The Led Zeppelin vocalist and jazz-rock virtuoso are among the high-profile stars confirmed to appear with violinist Kennedy as he headlines the venue's Love Classical festival on Tuesday, March 14.
Other guests announced include violinists Michael Guttman and Pieter Daniel, Bulgarian gadulka player Georgi Andreev, and Kennedy's own ensemble, the Orchestra of Life.
Lucy Noble, artistic director at the Royal Albert Hall said: "We're incredibly excited to be announcing this amazing collaboration between one of Britain's greatest rock legends and a violinist who has spent his career pushing the boundaries of his art, creating incredible music that breaks down the boundaries between genres.
"This meeting of two of our most acclaimed musicians promises to be a once-in-a-lifetime experience, and with the likes of Jean Luc Ponty also confirmed for this gala celebration, it's destined to be an incredible night."
Robert Plant made appearances with Led Zeppelin in 1969 and 1970 at the iconic London venue, later returning as a solo headliner. He first worked with Kennedy on his album Fate of Nations'in 1993.
The exact details of Nigel Kennedy and Friends: Gala Celebration are being kept under wraps, but the show is expected to include Bach, Vivaldi, jazz, world music and a tribute to Jimi Hendrix, who made his first appearance at the Royal Albert Hall 40 years ago.
Love Classical runs from March 4-17 and includes headline shows from Kennedy, pianist Lang Lang, and Classic BRIT-winner, Alison Balsom, among the 21 shows across seven spaces.
