Coda is the only Led Zeppelin deluxe edition to include two companion discs, featuring 15 tracks recorded between 1968 and 1974. They include the frenetic blues jam “Sugar Mama,” recorded in 1968 at Olympic Studios during sessions for the band’s eponymous debut and the previously unreleased “St. Tristan’s Sword,” a rollicking instrumental recorded during the Led Zeppelin III sessions in 1970. “Friends” and “Four Hands” were recorded with Indian musicians on Plant & Page’s 1972 trip to India. Among the many other highlights featured here is an early version of “When The Levee Breaks” from 1970 titled “If It Keeps On Raining.”
