A decade ago, I launched a column with Pigeons and Planes called 5 On It. Each Saturday for two years, I wrote about my favorite rap discoveries and fixations from the preceding week. It has been almost seven years since I last wrote about music in the way I did for P&P, as much wannabe critic as ad hoc historian and industry theorist. I have not had a desire to return to the kind of music coverage that focuses on “discovery” until recent weeks, as the media landscape continues its necrotic metamorphosis, leaving gaps once filled by passionate, talented people looking to highlight music and art that might not otherwise find its way to the attention of the public.
