Watch the Pack of Lies online guitar lesson by Mimi Fox from Jazz Performance
Listening to Wes Montgomery is a great way to learn Chordal Soloing. Another way to start getting it under your fingers is to be sure you know your chords in every inversion everywhere on the neck. My book "Guitar Arpeggio Studies On Jazz Standards"(Mel Bay Publications) has three pages of essential chord voicings for jazz guitar. I am also a big believer in playing the drums so that you can put hip rhythms with your cool voicings.
