In April 2005, Lesh's book "Searching for the Sound: My Life with the Grateful Dead" () was published. The book takes its name from the lyrics of a Grateful Dead song titled "Unbroken Chain," from their album "From the Mars Hotel". "Unbroken Chain" is one of the few songs Lesh sings. This was the only book about the Grateful Dead written by a member of the band until 2015, when Bill Kreutzmann released his memoir, "Deal: My Three Decades of Drumming, Dreams and Drugs with the Grateful Dead".
