COMING ATTRACTIONS

Poor ticket sales have plagued the “Monsters of Rock” tour since it started back East a few weeks ago, causing promoters to abandon plans for second shows last weekend at San Francisco’s Candlestick Park and the July 23-24 weekend at the Los Angeles Memorial Coliseum. The marathon show--consisting of 10 hours of Van Halen, Scorpions, Dokken, Metallica and Kingdom Come--will be held at the Coliseum only on July 23. Steve Rennie, a spokesman for Avalon Attractions, which is sponsoring the local date, said ticket prices, which cost up to $28.50, may be a factor in the poor sales. He said attendance could have been better around the country if Van Halen had started the tour later in the summer--thus allowing the group’s latest album (which is No. 1 this week) to build interest in the shows.
