The 2013 Mad Decent Block Party kicks off on July 19 in Calgary; please keep in mind that, while this is the full lineup, not all of these artists will be at each stop. We heard that tickets were going to be $30, and judging by the date that was given last week, could be going on sale on May 3. We'll keep you posted.

UPDATE This isn't even the full lineup! DOUBLE UPDATE Hit Page 2 to see which artists will be performing in which cities.
