Source: As listed on the back cover. As stated in an earlier post, Dio did not tour Japan until later in 1986 – save for one festival experience in July of ’85 – so, it can safely be stated that this is not a Japanese concert recording. Irvine Meadows amphitheater just saw its last concert on October 30th, 2016 and will be turned into apartment buildings. Ozzy Osbourne recorded the Japan only (until 2012) video Speak Of The Devil here in June of 1982.
Quality is quite decent.
