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, 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 opportunites and things for us to do. But more importantly, I think, than all of that, is it was a really cool time when the four of us were really, probably, our most connected together as a band." MEGADETH's fifth LP, "Countdown To Extinction" was released on July 14, 1992 through Capitol Records. The band's best-selling full-length CD to date, it was certified double-platinum by the RIAA (Recording Industry Association Of America) for U.S. shipments in excess of two million copies. The album also produced the band's most successful hit singles, "Symphony Of Destruction", "Sweating Bullets", "Skin O' My Teeth" and "Foreclosure Of A Dream". Gigantour — the critically acclaimed package festival founded in 2005 by MEGADETH — made its highly anticipated return for the first time since 2008. The multi-artist bill kicked off on January 26 in Camden, New Jersey and wrapped on March 3 in Austin. MEGADETH was among the nominees for the 54th annual Grammy Awards, which was held on February 12 at Staples Center in Los Angeles. The band's tenth Grammy nomination was for its new single, "Public Enemy No. 1", off MEGADETH's latest album, "TH1RT3EN", which came out on November 1, 2011. "Public Enemy No. 1" actually marked the second Grammy nomination for music from "TH1RT3EN", as the song "Sudden Death" was first unveiled in the 2010 video game "Guitar Hero: Warriors of Rock" and received a "Best Metal Performance" nod.
