I wanted to find the heaviest organ sounding album possible, and I believe I found it: Oliver Messiaen's "Méditations" with him playing the organ at the Church of Sainte Trinité. Messiaen is a composer that I know very little of but wasn't much of a laughing guy. This is meditation in the religious sense, where one focuses on the nature of a God in a church and reflecting on the offshoots of such a belief. Think St. Thomas Aquinas.
On the other hand, I get off on Messiaen's organ playing and the majestic overpowering sense of power out of his instrument and his skill as a composer. It's not all bombast and power, there are quiet moments as well, but having this album in full volume is clearly a tunnel from one side (my home and turntable) to God.
