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 us: "Because there was only 6 songs, because the lengths were very long, it meant that there were only going to be 6 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."
