Most second leg dates to go on sale July 8 and 9.

System of a Down is adding a second leg to its current North American summer tour.

The current leg, which closes Sept. 1 at the Air Canada Center in Toronto, will be followed by a set of new dates beginning Sept. 17 at the Pacific Coliseum in Vancouver.

A total of ten second leg dates running through mid-October have been announced so far, including several stops in Canada, the Midwest and Northwest.

Most second leg dates will go on sale this weekend (July 8 and 9) and will be priced from $32.50 to $45.

Mars Volta, already touring with System of a Down this summer, will also be part of the new leg. A third band is expected to open the new shows.

System of a Down is booked by Creative Artists Agency.
