Watch the Blues for Two online guitar lesson by TrueFire from Play Jazz Guitar 6: Soloing Approaches
Blues for Two - Diminished Movement is a video guitar lesson presented by Mimi Fox and is sourced from Jazz Performance.
If you get my book, "Graduated Soloing: The Mimi Fox Guitar Method"(Mel Bay Publications), you will find many hip diminished exercises to study and play. These can be integrated into your own soloing. The diminished chord, and diminished runs were used a lot by the great Gypsy guitarist Django Reinhardt and his music is really fun to play I recommend you pick up some of his original music to hear how the diminished chord/scales can be used in compositions.
