Soundgarden’s first concert tour in 15 years will begin north of the border. The first four dates have been announced, beginning with a July 2 show at Toronto’s Molson Canadian Amphitheatre. Subsequent shows will bring the Seattle band to Philadelphia, Denver, and Los Angeles. Tickets go on sale Monday, and more dates are expected to be announced soon. Soundgarden reunited last January and performed at last summer’s Lollapalooza festival.
