While more than a dozen wildfires burned from the Mexican border to Los Angeles yesterday (Oct. 23), many concerts throughout the area have been canceled or postponed.

At deadline, Los Angeles-based concert promoters AEG Live (and subsidiary Goldenvoice) and Nederlander Concerts hadn't reported any concert cancellations in Southern California. But the wind-driven blazes, which have already forced a reported half-million people to evacuate their homes, have caused Live Nation to cancel or postpone most concerts scheduled for this week, according to company officials.

"We will continue to monitor the situation," Nick Masters, president of Live Nation's Southern California music operations, tells Billboard.com. "Our hearts go out to those affected by the fires."

So far, a Jennifer Lopez/Marc Anthony concert, originally scheduled for today at San Diego's Cox Arena, has been moved to Nov. 10. Meanwhile, a Jesus and Mary Chain gig at San Diego's 4th & B today has been cancelled. Ticket refunds for the latter are available at point of purchase.

At Live Nation-owned House of Blues San Diego, shows by the Pack (today) and Peter Frampton (Oct. 26) have been canceled or postponed, while a Chevelle (today) concert at SOMA has been canceled.

Other San Diego venues affected by the wildfires include Belly Up Tavern and the Casbah.
