Lesser known variations of the sicilian for black?

What are some good ways for black to jump off the main line of the sicilian? I like the sicilian in general, but I really, really dislike how both my opponent and I seem to know (more or less) exactly how it will look 20sh moves down the road, and I think I'd like playing it more if only I knew how the game would look that far down the road, and leave my opponent guessing.

Recommendations?

Currently I play the sicilian dragon, or the najdorf

It is usually said that with the Sicilian Kan, both sides can start playing chess early, alot earlier than most other sicilian variations.

But I've never touched it, so don't take my word for it.

I think it's worth saying that I'm not looking for an easier variation of the sicilian - quite the opposite, I'm looking for a harder variation, one that my opponent is less likely to be prepared for, and so the fact that I have spent time studying it should give me a nice advantage in the opening.

Also, an "unusual" response opening to e4 would be welcome. I've toyed with all the responses I know - I've tried the French, King's pawn, Pirc (Absolutely hated that one as it's almost entirely defense), Scandinavian, Caro Kann, Sicilian, and the Alekhine. Any other recommendations?

Modern. It's a more versatile Pirc

for silician kan, okelly, taimnov , or paulsen varitaions should all be ok for black some of these lines are quite interesting

If you know your opponent plays the open Sicilian, give 1. e4 c5 2. Nf3 Nf6 a look. It's a rather rare continuation and can be quite good against an unprepared opponent. White can transpose to the main line of the Alapin after 3. e5 Nd5 4. c3, so if your usual reply to the Alapin is 2...d5 or 2...e6, it might cause some headaches, but other than that, it's fighting chess.

Unusual response to e4? b5!?  almost never played, but IMO, it does have a little sting.

After Bxb5 Bb7 White has to start looking after his e pawn and Black gets nice developement for the pawn.  And there is NO theory :)

 If you want something unusual play the Nimzowitsch- 1.e4 Nc6! 2.d4 d5 - It's a very underrated opening

i would suggest you to have a look at polgar's sicilian games from the last world cup. she played rare line(s)?!

Play the Dragadorf (...g6 followed by ...a6 and ...b5). You already play Najdorf and Dragon so you'll have a good feel for the positions (sometimes it plays more like a najdorf, sometimes more like a chinese dragon), theory has developed a lot over the last few years but White players often don't know anything about it.

You can go for taimonv,  Scheveningen Variation( this variation might transpose into the morxy bind), classic or old, but personally just use dragon, accelerated dragon or najdorf, or taimonov

very good chess opening in chess.com

O'Kelly variation. If White doesn't know what they're doing they get a bad game right from the start. And if they do, it's still sound and interesting. There's a good chapter in Dangerous Weapons: The Sicilian, which is all you need to start playing it.

Has oozecube2 been here since 2010?

agreed, except these days most players dont take the bait and play 2.nf3 or 2.nc3

How about the Brussels Gambit? It's dubious, but it's also one of, the least played in most databases, and has a relatively high win rate for black.

It also kinda looks like a reverse vampire gambit.
