KC Turner Presents Cookout Concert Series: Led by acclaimed guitarist-singer Stu Allen (of Phil Lesh & Friends, Melvin Seals & JGB) on guitar, a revolving cast of incredibly talented musicians inhabits Mars Hotel, drawing from the Grateful Dead’s vast catalog to delight Deadheads and music fans of all generations. A Mars Hotel show is always an energetic evening of good vibes, good music, and good community. When it became apparent that Jerry Garcia had played his final show in 1995, Stu Allen began working to keep Garcia’s music, sound, and spirit alive in the concert setting.
