Anything and everything that falls under the progressive rock genre, (i.e. Emerson Lake and Palmer, Yes, Frank Zappa, King Crimson). I think if more young people listened to this music, like me, they might really catch onto it, if introduced to it slowly. The more expiremental it is, the easier it might scare someone off.

If you're interested, I suggest you start with Pink Floyd (which is considerably more mainstream), if you haven't already. Or you could try Supertramp first.

From there try out Yes, King Crimson, or Emerson, Lake and Palmer (perhaps early Genesis as well, ignoring anything past "Wind and Wuthering").

And, if you really want to try out incredibly expirmental material, there is no one better than the legendary Frank Zappa.

Outside of the progressive genre, I like Dexys Midnight Runners, which are sadly only remembered as writing "Come on Eileen." Some even call them one hit wonders, which is truly a despicable label. Anything from their first two albums is excellent.

Another all too readily labeled "one hit wonder band" is Men at Work, which also have tons of good material other than the big singles like "Down Under" that they are mostly remebered for.
