<p>Mine is either Sgt. Pepper or Dark Side of the Moon/The Wall (depends on the day). I have gained a greater respect for Green Day’s American Idiot, but there are two or three songs that are too opera rock for me. </p>
<p>Sgt. Pepper is up there because it was the first prominent experimental album, and influenced bands like Pink Floyd. I like the psych rock genre more on concept albums.</p>
<p>the downward spiral</p>
<p>Between the Buried and Me - Colors
Dream Theater - Scenes from Memory
Helloween - Keeper of the Seven Keys: The Legacy
Estatic Fear - A Sombre Dance
Persefone - Core</p>
<p>Definitely Sgt. Pepper’s, but also:</p>
<ul>
<li>The Wall, Pink Floyd (Great Musical, too)</li>
<li>In The Wee Small Hours, Frank Sinatra</li>
</ul>

<p>Stole my answer XD</p>
<p>The Human Equation - Ayreon. Probably the epitome of rock opera.</p>
<p>Out of recent albums, The Suburbs by Arcade Fire is phenomenal.</p>
<p>Sgt Pepper sucks.</p>
<p>Klaatu - Hope</p>
<p>^I just looked it up on Amazon. Better check it out</p>
<p>“It’s Complicated Being a Wizard” by Portugal the Man.</p>
<p>Is that a fact, rymd?</p>
<p>Favorite would be Mars Volta’s debut and all three of The Dear Hunter’s albums.</p>
<p>The Dear Hunter stuff</p>
<p>Dream Theater’s Metropolis Part 2: Scenes From a Memory is probably my favorite album of all time. Dance of Eternity is just insane.</p>
