Songfacts®:

• This is the initial song to be released from Worship Music, the tenth studio album by American thrash metal band Anthrax. It was their first album of original material since 2003's We've Come for You All.
• Anthrax fans had a long wait to hear new material from the band. The album was originally going to be released in May 2009, but after various delays it finally came out on September 12, 2011 internationally and September 13 in the US. This song was released on June 24, 2011 as a free download on anthrax.com as a way to say "thank you" to fans' loyalty in waiting in anticipation for Worship Music.
• Anthrax lead guitarist Rob Caggiano told Guitar World about this tune: "That was kind of the first song we started playing as a band, even in the rehearsal room. It was one of the first songs that got finished, so we started playing it a lot. It's a song that's got all the elements of what the band is about; it's got the thrashy vibe, it's got melody, it's got a groove, it's got a lot of over-the-top playing in it."
• Joey Belladonna, who was lead singer of Anthrax from 1984-1992, performs the vocals for Worship Music, making it the first Anthrax album to feature him since 1990's Persistence of Time.
• In our interview with Anthrax drummer Charlie Benante, he recalled guitarist Scott Ian "being really excited back when we got together and started writing." The stickman added: "He was excited about the riffs. If there's one thing about Scott, he loves a fast fu--in' riff. He either loves a real fast riff or real heavy type of riff. So with 'Fight 'Em,' I could tell that he was really happy about, 'This is going to be a new Anthrax song.'"
