I'm not too upset missing Swashbuckle, and with Blackguard there's always next month.
I remember there being a few other bands on the tour that weren't able to make the Toronto date.
04/24 - Nile
05/18 - Abigail Williams
06/20 - Negura Bunget
07/04 - Agalloch
08/23 - Alice in Chains
12/06 - the Music of Final Fantasy
