Hi Steve,
Three firm recommendations come immediately to mind:
* For chord voicings and usage in a wonderfully practical and relatively minimalistic way - I have not found better ( or more fun to apply ) than The Joe Pass Chord Book. Each section of this slim book is divided into Major sounds, Minor sounds etc. A simple but most usable way of looking at the way that all things are relative in chord voicings - and is a great way to find/ collect / adapt voicings for making your own stuff. My personal 'Bible' on the whole subject.
* For appreciating how to tastefully develop deceptively simple ( and very tuneful ) ideas from basic materials - and then be helped understand where you can take it for yourself:
Larry Carlton 'Hot Licks' Volume 1 ( DVD ) :
Great for introducing more advanced soloing concepts in a simple and enjoyable way .
Larry Carlton -' 335 Blues' ( Interactive 3 CD-Rom package ).
A comprehensive expose of Larry's methods, tools and attitudes. A fine player and relaxed, skillfull teacher. I live in the U.K. - but they sent this boxed set quickly from the States, - and at a very affordable price. :)
It's nice to hear someone on the forum asking for Larry , Robben - and this form of music .
