The band opened with 2015’s “Repentless,” the title track of what is apparently its final album, and concluded - as usual - with 1986’s “Angel of Death,” an almost insanely fast-paced song about the horrific surgical experiments conducted by the Nazis at the Auschwitz concentration camp during World War II. Playing with characteristic precision and an equally characteristic absence of frills and fuss - apart from the 10 songs that employed fiery pyrotechnics - Slayer ripped through 19 selections in just under 90 minutes.
