Armenian-American heavy metal band System of A Down are currently on a South American tour, and this past Wednesday, April 30 they played a show in Ñuñoa, Chile. At the beginning of Psycho from their Toxicity album, guitarist/vocalist Daron Malakian recited the chorus of Rush's Red Sector A before busting into the song. He says the line, All that we can do is just survive. All that we can do is help ourselves to stay alive twice. He then recites the lines, Are we the last ones left alive? Are we the only human beings to survive? twice. You can watch the performance below or on YouTube at this location at about the 1:10:50 mark. Thanks to Christian S for the heads up.
