Metalheads gathered last night (May 15) at Bowery Electric in New York City to celebrate the release of the book ‘Louder Than Hell: The Definitive Oral History of Metal.’

The night started out in a badass way, as outside of Bowery Electric a guy who was drunk on Four Loco got slugged by a biker ‘Sons of Anarchy’ style for knocking over his motorcycle.

Inside Bowery Electric, things got heated really quickly, too, as lovely burlesque dancers graced the stage -- first a gorgeous blonde followed by a vivacious red head.

Then it was time for the authors of ‘Louder Than Hell: The Definitive Oral History of Metal’ --Jon Wiederhorn and Katherine Turman (pictured above) -- to grace the stage to read excerpts of the book, including passages from Black Sabbath's Tony Iommi and Machine Head's Robb Flynn. The crowd’s knowledge was put to the test as a game of heavy metal trivia was played in exchange for prizes.

Finally, metal band Acrassicauda, hailing from Iraq, shook the foundation of the venue with their thrashy fusion metal vibe. Their piercing riffs, eclectic drum patterns and unique vocals made for an infectious sound that the crowd definitely dug.

The noise coming from Bowery Electric was a fitting way of celebrating the new book ‘Louder Than Hell,' which tells the story of heavy metal through the bands and artists themselves. You can order the hardcover or kindle edition at Amazon.com and find out more about the book here.
