It was the brat green croc heels in front of me that did it. Outside, Hurricane Ernesto was raging, the rain twirling on and off in the cloudy late afternoon. The weather had already forced the Canadian DJ Dan Snaith to abandon plans of spinning at a semi-impromptu “block party” on Jefferson Street, between Wyckoff and Irving Avenue. It was part of a free series that Snaith — who got started under the moniker Manitoba but later changed that to Caribou following the threat of litigation from punk singer “Richard Manitoba” — had been putting on that weekend, stopping by Philadelphia, Toronto and Chicago, before landing in Bushwick.
