Which band's 2004 album 'Ashes of the Wake' is a concept album about war?

Lamb of God released the 2004 war-themed album Ashes of the Wake. It was the American band's fourth studio album and its first major-label release, arriving through Epic Records on August 31, 2004.

The album draws heavily on the Iraq and Afghanistan wars. Its title track incorporates interview audio from former U.S. Marine Staff Sergeant Jimmy Massey, while songs such as "Now You've Got Something to Die For," "One Gun," and "The Faded Line" criticize militarism, political leadership, and the human cost of war. The album is often called a concept or anti-war record, although its songs also address subjects such as organized crime and tensions within the band.

Lamb of God recorded the album with producer Machine. It became a breakthrough release, debuting at number 27 on the Billboard 200 and eventually becoming the band's best-selling album. Common mix-ups include confusing Lamb of God with other 2000s American metal bands such as Killswitch Engage or Trivium; neither released Ashes of the Wake.
