Organizers of Bluesfest in Ottawa were caught off guard when they discovered this year's lineup was already online.

"It did force our hand a day or two early, but honestly it wasn't the end of the world," says executive director Mark Monahan.

The list of artists was on a developmental website and apparently found by a blogger, who posted it online. But it could've been worse for organizers.

"The bands that they found actually were the right bands," says Monahan. "There were some others there they could've found that weren't."

A few of the bands coming had already been announced by the festival, including Keith Urban. But others had leaked over the past couple of weeks.

"It's really difficult to not have all the agents, all the managers, all the sponsors at least leak something," says Monahan, who's relieved the lineup is finally public.

So who's coming? Jason Aldean joins Urban and Ottawa's Kira Isabella in the country department. Iggy Azalea will rock the capital, as will Skrillez and Diplo. The Tragically Hip, Hedley and the Arkells will also be on hand.
