According to Soundsblog.it, MOTÖRHEAD canceled this past Saturday's (June 22) appearance in Austria at the See-Rock festival and the June 25 show in Milan, Italy, due to an unspecified "haematoma" suffered by the band's frontman, Lemmy Kilmister.The news was first broken by the See-Rock festival web site, and then the promoters of the Milan show confirmed the health issue. A haematoma is a localized collection of blood outside the blood vessels usually in liquid form within the tissue. It can happen on any part of the body, with different degrees of heath consequences. It was revealed in the latest issue of U.K.'s Classic Rock magazine that \ Kilmister recently had a defibrillator fitted — an operation to put a device in his chest to help his heart beat normally — after experiencing "heart problems." MOTÖRHEAD has set "Aftershock" as the title of its new album, tentatively due in September. The follow-up to 2010's "The Wörld Is Yours" was recorded at Maple Sound Studios in Santa Ana, California with longtime producer Cameron Webb and will feature 13 songs, including "Dust And Glass", "Knife", "Going To Mexico", "Lost Woman Blues", "Death Machine" and "Heartbreaker".
