Boston public radio station WBUR is dropping its arts reviews. The station is “eliminating its online arts magazine, Arts Scene, and with it the position held by editor and arts critic Bill Marx. The station has, however, added a full-time arts reporter, Andrea Shea. Arts criticism will be phased out by the end of the summer. ‘It was a good service for people who really like in-depth criticism and commentary in the arts. There’s a role for that, it just isn’t completely tied into what our main mission is’.”
