The Eskalators had another Subway Show this past weekend. This time it was an 7 Train-themed singalong (Ozzy’s “Crazy Train,” Tom Waits’s “Downtown Train,” the Clash’s “Train in Vain,” etc) that ended up at Flushing Meadows Park, where an impromptu Round Robin four-band took place with Aa, Pterodactyl, and Terror Pigeon Dance Revolt. Rebecca Smeyne documented all that, plus a dolphin.
