I still can't get behind Bitches Brew. It's just too much.
Have you listened to In a Silent Way? It's a bit more relaxed/ambient than Bitches Brew.
Luckily my wife went down the jazz hole at the same time I did, and I can put on something like Bitches Brew or On the Corner without complaints.

My very young kids and wife seem to quite like/tolerate Jazz.
Bitches Brew got a bit much for them though.
