Unlike Nielsen SoundScan figures, Boxscore numbers depend on the consistency and accuracy of reports from promoters, venues, agents and managers, and represent just a fraction of the overall value of the live business. Therefore, if Boxscore only shows us a slice of what's actually going on out there, the metric is still a useful barometer for gauging the overall health of the industry. If nothing else, Boxscore brings numeric context to what those in the trenches have been telling us all year—and those two metrics don't always run in parallel.
But this year, numerous indicators, including the Boxscore chart, point to a robust business that is still very much in growth mode. In fact, with all the non-reporting tours, concerts, events, soft-ticket shows, casinos, private concerts and international plays, the touring industry is surely at its highest level ever, with fans worldwide ponying up a conservative Billboard estimate of more than $15 billion annually for the in-the-moment experience that only live performance can offer.
Only a bit more than a tenth of all shows gets reported to Billboard.
The label has to track concert gross, so there's no real point in sending that out to anyone except investors. Sales/airplay/streaming/etc. are not tracked by labels, and that is why Nielsen Soundscan/Billboard exists.
