Why festivals and tours need modelling before collection
The two structures that make this source interesting are also the two that break a naive collector, and both have to be decided before the first request rather than cleaned up after.
Tours first. A tour is a sequence of dates by one artist, and knowing that six listings belong to one run changes what they mean: it is one commercial decision rather than six. Where the platform states the tour, capturing it is nearly free. Reconstructed later from artist and date proximity it is guesswork, and it is wrong exactly when an artist plays two cities in one week for unrelated reasons.
Festivals second. A three day festival with forty artists across several stages, sold as day tickets and full passes, is not comparable to a Tuesday night club show, and any average that contains both describes neither. Typed separately, both are usable; merged, the festivals dominate every artist count and the concerts dominate every event count.
The third reason is that artist-first organisation makes this a good source for coverage questions: which artists tour Spain, how often, in which cities, and how that compares with neighbouring markets.
The fourth is scope. Wegow is strong in Spain and lighter elsewhere, so it is a Spanish live music source with European coverage rather than a European source, and we describe it that way.
