We are counting down the days until Metallica‘s James Hetfield and Kurt Hammett return here In the Studio September 12 to host the twenty-fifth anniversary of one of rock’s most massively popular efforts, “the Black Album“! To warm up, flashback to the fiftieth anniversary of that most American of worldwide exports, the Super Bowl, & the site was one of America’s finest regions, the San Francisco Bay area. And so who did the the NFL secure to perform at halftime during this historic All-American sporting event, broadcast to over a billion viewers worldwide from a city with a long rich heritage of musical contributions? Coldplay, the finest British innocuous band money can buy.In the true spirit of rock marching to the beat of its own drummer (in this case the Olympian Lars Ulrich), San Francisco homies Metallica decided to play the night before the Super Bowl in AT & T Park for a crowd even larger than that for the football game, and they got to play for two hours in a thrash metal throwdown, neither of which would be possible in a Super Bowl halftime performance. And even if you missed it, the spectacular sounding concert is available for download or compact disc at http://www.livemetallica.com . Here is heavy rock absolution with “The Unforgiven“.
