Though The Byrds’ final years were sometimes rocky, this spirited live album proves they found new vigor onstage thanks to the addition of guitarist Clarence White. Recognizing his young charge’s skillset for both bluegrass and hard rock, leader Roger McGuinn put him to equally sterling use on “Black Mountain Rag/Soldier’s Joy”—a medley of traditional Appalachian tunes—and the jammy, 18-minute take on “Eight Miles High” that provided a suitably heroic climax for one of The Byrds’ last nights in London.
