Modest Mouse I would love to see. No dates announced after late May, other than Osheaga.
Beck rumours are fun.
Lady Gaga plays Montreal on July 2, and then nothing for five days. Also plays Toronto on July 9. Ottawa stop makes sense time wise. Seems like she would be the type of artist that would bust a massive chunk of the budget.
Wouldn't mind seeing Chvrches, but they're in Europe starting late June to play every European festival ever. There is a gap during Bluesfest with no dates, but that seems a stretch.
Few other Osheaga acts I'd love to see at Bluesfest... Outkast(I can dream, right?), Childish Gambino, J. Cole, Half Moon Run, Danny Brown, Hey Rosetta, Manchester Orchestra
