If you like Jack Bruce, then "Harmony Row" is a masterpiece, IMO. I'm a BIG fan, but admitidly, his music is not for everyone.
Songs for a Tailor is a classic in its own right. Some tunes to listen to are:
"Never Tell Your Mother she's Out of Tune" with L'Angelo Misterioso on guitar (a/k/a George Harrison). Remember, he's on Cream's "Badge", too.
"Theme for an Imaginary Western" made somewhat popular by Mountain.
"Rope Ladder to the Moon" covered really well by Colosseum
Spedding also has quite a few solo albums that are interesting, if nothing else. Check out "I'm Not Like Everybody Else".
