HEAVEN & HELL — the band featuring BLACK SABBATH members Tony Iommi (guitar), Ronnie James Dio (vocals), Geezer Butler (bass) and Vinny Appice (drums) — has announced the cancellation of all planned appearances this summer in Europe, including its headline set at Bloodstock's (U.K.) 10th anniversary festival as well as performances at Sonisphere in Switzerland, Czech Republic, Bulgaria, Romania and Turkey.The band has issued the following statement regading the cancellations: "We have to announce that all forthcoming HEAVEN & HELL European shows have been cancelled as sadly [vocalist] Ronnie [James Dio, who was diagnosed with stomach cancer in November 2009] isn't well enough to tour this summer. We hope that everyone understands and want to thank fans and industry colleagues for their continuing support at this time." HEAVEN & HELL guitarist Tony Iommi recently underwent stem-cell treatment on an injured hand. The band's drummer, Vinny Appice, went under the knife on November 30, 2009 for a shoulder injury sustained during the group's last tour. HEAVEN & HELL's debut album, "The Devil You Know", entered The Billboard 200 chart at position No. 8 with first-week sales of 30,000 units. The band's June 16, 2009 concert at Museumsmeile in Bonn, Germany was professionally filmed by WDR's (German public TV) series "Rockpalast" and was premiered on July 13, 2009. Watch the "Follow The Tears" performance below. In a recent online posting, Ronnie James Dio's wife/manager Wendy Dio revealed that there are plans to release a 30th-anniversary BLACK SABBATH "Heaven And Hell" DVD sometime this year. The package is expected to include brand new interviews that Ronnie, Geezer and Appice gave to Eddie Trunk — co-host of the VH1 Classic television program "That Metal Show" — on January 22, 2010 in Los Angeles, as well other extras.
