So I already know the answer to this, but;
I was originally introduced to Porcupine Tree years ago with Deadwing, and soon after In Absentia and Fear of A Blank Planet. With The Incident, I wasn't following the band closely enough to know when it was coming out, but was to know that it was on its way, and to know a few details. I happened to be in a music store the week of its release, and bought it sight unseen. I greatly enjoyed it. As time went on, I decided to go back into their catalog, beginning with Lightbulb Sun months ago (maybe a year or slightly more, I don't remember), which I bought the DVD-A version of, and within the last month, Stupid Dream, which I first heard a track from a couple of weeks ago, and immediately bought the DVD-A version.
Long story short, should I check out Signify? If so, what are the odds of me enjoying the albums prior to that?
