When you think of the gritty and poetic New York punk-rock matriarch Patti Smith, you probably don’t also think of a groovy poolside stage by the beach, but that’s exactly what’s set to happen Sept. 8. The woman who gave the world “Dream of Life” (one of her finest albums) will perform live with her trio at the Dream Inn, in the latest of the Dream Inn’s “vertical concert” series. Tickets are predictably pricey, because they include a room with a view of the show and a one-of-a-kind experience. (Things start just under $600 and the primo seats touch four figures, though divided among four people, the maximum head count per room, maybe that’s doable). But here’s a pro tip: If past vertical shows are any indication, you can hear pretty well from Cowell Beach.
