Megadeth will perform its 1992 album, "Countdown To Extinction", in its entirety on September 7 at Teatro Caupolican in Santiago, Chile. Speaking to the Artisan News, David Ellefson stated about the LP, "'Countdown' was really one of my favorite records of the whole Megadeth catalog... for a number of reasons. Musically, I think it brought together the best of thrash, the melodic part, writing big, hooky riffs. And that record really launched us into the mainstream, which opened up a lot of other opportunities and things for us to do." Watch the following VIDEO from Artisan News.
