This was the opening track of American progressive metal band Dream Theater's tenth studio album, Black Clouds & Silver Linings
. It's 16-minutes long, which explains the "Progressive" in Dream Theater's "Progressive Metal" label. The album contains just 6 songs, and it covers some pretty heavy stuff. Their drummer Mike Portnoy
told Songfacts: "Because there was only 6 songs, because the lengths were very long, it meant that there were only going to be six subject matters. Normally if we have more songs on the album, we're able to cover more lyrical ground. But with only six songs, inevitably the topics are heavy."
