Jann Arden headlines a Calgary unity concert a month before Alberta's separation vote

A free outdoor concert headlined by Jann Arden brought thousands to downtown Calgary on Sunday, staged in support of Canadian unity — about a month before Albertans cast ballots on the question of separation.

The timing is the story: a mass gathering in Alberta, organized around the country staying together, landing in the final stretch before a vote that asks whether it should. A concert doesn't decide a referendum, but thousands turning out for a free Sunday show is a visible, countable thing.
