Orange County, California's AVENGED SEVENFOLD has released the following statement:"Due to technical issues beyond our control, the [the previously announced July 31] webcast of AVENGED SEVENFOLD [from Syracuse, New York] has had to be canceled. We have been working non-stop to resolve these issues however there are circumstances beyond our control. "We realize how disappointing this is to our fans and feel horrible that we could not have these issues resolved in time. We were hoping to make this a special event for M. Shadows' [vocals] birthday. Unfortunately, he has been trying to resolve these issues when he should be celebrating with his fans. "We will make every effort to bring a live show to the web as soon as possible and appreciate the support of all fans. We are just as disappointed as everyone." AVENGED SEVENFOLD performed live for the first time since the death last December of drummer Jimmy "The Rev" Sullivan this past Sunday (July 25), when the band played at the Heavy MTL festival in Montreal, Quebec, Canada. Behind the drum kit was DREAM THEATER's Mike Portnoy, who made his live debut with the group after doing the drum parts on their newly released album, "Nightmare". "Nightmare", AVENGED SEVENFOLD's fifth album, arrived in stores on Tuesday (July 27). It follows up the band's self-titled 2007 effort. The record could debut at No. 1 on next week's Billboard album chart if sales projections are right. Portnoy is committed to playing on all the group's 2010 tour dates. AVENGED SEVENFOLD will co-headline this summer's inaugural Uproar Festival tour with DISTURBED and STONE SOUR, beginning on August 17 in Minneapolis.
