Anything Blues that goes beyond the basic swing/shuffle
Latin blues
Mambo blues
Rhumba blues
Slow 12/8 blues
6/8 blues
Gospel blues
You get the drift
+1, the more blues styles the better IMHO!
And not just styles, realtracks. Blues bass realtracks and blues organ realtracks in particular, many of the blues styles currently available tend to reuse the same bass and organ realtracks.
+1
Albert King: Crosscut Saw, rhumba style
Albert King: Oh Pretty Woman -style
Albert King: Born Under A Bad Sign-style
BB King, jumping bas shuffle-style : Waiting On You, from Blues Is King
BB King, The juicy organ ballad style of : Dont Answer The Door, from Blues Is King
Yes - we have more than enough Country Real Tracks and Styles to last us a lifetime. Now it's time for some more Blues.
Yes please!! Blues organ solo, Jump Blues ( with a correct 2-5 bassline), Authentic Chicago (Jimmie Rodgers, Robert Jr.Lockwood) Blues, Rhumba Blues, Blues horns, Blues harp would be nice but after the previous version I'm a little dubious. Authentic blues rhythm guitar a la west coast players like Hollywood Fats, Jr. Watson, Kid Ramos.
+1 On the Latin, etc. blues styles request.
You also hear a lot of Latin rhythms in 50's and 60's rock n' roll. Some Latin rock n' roll Real Tracks/Drums/Styles would also be great.
I agree with all the above suggestions and please don't forget about:
* Blues Brass Real Tracks - in the style of BB King, Roomful of Blues, Albert King (I'm sure you could convince the three guys in Roomful of Blues Brass Section to visit your studio for half a day).
* Rhumba Blues Real Tracks/Drums
* Blues Rhythm Guitar Real Tracks in style of Jimmie Rodgers
* Blues Organ Solo Real Tracks
* Blues Harp Soloist in style of Little Walter, Big Walter Horton, James Cotton
