"Three decades later, Coda is the unlikely closing triumph in Page's series of deluxe Zeppelin reissues: a dynamic pocket history in rarities, across three discs with 15 bonus tracks, of his band's epic-blues achievement. There are familiar strays, such as "Baby Come On Home," from the sessions for 1969's Led Zeppelin, and the 1970 B side "Hey, Hey, What Can I Do." But Page has gone deep. "Sugar Mama," cut for and left off Led Zeppelin, already suggests the tightly wound textural fury of Led Zeppelin II. "If It Keeps On Raining" is a truly alternate take of "When the Levee Breaks," on Led Zeppelin IV - less titanic, with more worried-blues nuance in Plant's vocal - and two long-bootlegged 1972 recordings by Page and Plant, made in India with members of the Bombay Orchestra, evoke their determined exploration of the global routes and branches in American blues and Celtic folk, on the way to the rugged spectacle of 1975's Physical Graffiti".
