From “Loose Lucy,” the Deadcast jumps onto Dead tour in June ‘74, going under the hood of Phil Lesh’s new quad bass, behind the scenes at the tie-dye information booth, a private lunch at the Bank of Boston, & on a Mars Hotel-soundtracked summer road trip with Sonic Youth’s Lee Ranaldo.

The Deadcast explores Phil Lesh’s masterpiece “Unbroken Chain,” its mysterious lyricist Bobby Petersen, & digs into the luminous synth with Ned Lagin himself; plus, the story of the album title & art with the Grateful Dead Records crew & a visit from Animal Collective’s Avey Tare.
