New York Post: The troubling string of departures from Jay Z’s Tidal music streaming service is said to be getting longer with the exit of two more high-ranking execs. Zena Burns, Tidal’s head of label and artist relations, reportedly left the company last week after just two months on the job. Also, Tidal chief marketing officer Jeff Geisler is said to have left the company, heading to Saatchi & Saatchi for a similar role.
