I very much liked Steven Johnson’s piece on the failure of the feared creative apocalypse to materialize. I do have a bone to pick, however: you do not write things like this:
"According to one source, the top 100 tours of 2000 captured 90 percent of all revenue, while today the top 100 capture only 43 percent."
without either naming the source or providing a link. As it happens, however, a bit of searching does lead to the actual source — Pollstar, whose concert revenue data do suggest a decline in the dominance of live music by the biggest acts.
