Lots of good info above - roachboy is right in in his characterization of styles and forms. By the way, it is thought (commonly) that Bach did not write the Toccata and Fugue in d minor. The most plausible suggestion I've heard is Mendelssohn, who really introduced Bach's music to the world about 50 years after his (Bach's) death. Since you like the Toccata and Fugue in d minor, there are others, but I'd really suggest finding a recording of Bach's Passacaglia and Fugue in c minor - it is fantastic! Alternatively check out orchestrations of the organ music - Leopold Stokowski did some intersting ones. There is also a recording of an orchestration by Henry Wood recorded live at the Proms concerts in London by the BBC orchestra in 1997. This will be the piece you are familiar with played by an orchestra - like a painting of familiar shapes, but in different colors. If you like the organ and are willing to stretch your limits, check out the music of Olivier Messaen. It is 20th century stuff, and more abstract, but the power and color are undeniable.

*music lesson*

Toccata is a style of keyboard piece that is typically quite technical in nature. Toccata means "touch" and I guess the name sticks because of the technique required to play the pieces. The fugue is a form based on repetitions (called entrances) of a theme (called subject) and its accompanying music (countersubject). The point of it is that the composer creates a big piece of music out of limited material with limited means of manipulating it. Virtually all music students are required to write fugues to get degrees - and it is seen as a painful rite of passage, since it isn't easy! The toccata and fugue (which is not a style, just a couple of pieces with unimaginative titles) is literally that - a toccata section as introduction followed by a fugal section (which is about twice as long if memory serves).
