This week, the trio discusses the work and legacy of a band you may have heard of, Led Zeppelin— one of the most popular and innovative rock bands ever. Initially called the New Yardbirds, Led Zeppelin was formed in 1968 by English guitarist Jimmy Page before taking the United States by storm. In addition to Page, the group included vocalist Robert Plant, bassist/keyboardist John Paul Jones, and drummer John Bonham.  The band's blues roots frequently gave way to heavy folk, psychedelic rock, and orchestral detours— a  testament to the group's versatility and willingness to push sonic boundaries. Scott says, "It's less about the technical difficulty and more about the aesthetic."  Tune in for more music and ideas, brought to you by onlinegreatbooks.com.
