Slow Blues - A minor Pentatonic, D dorian and E Superlocrian scales are used over the groove. In this video are very good ideas (phrasing) for expanding your vocabular when playing rock and blues guitar. Just by adding a blue note or a minor note you can change the mood within your phrasing... even omiting notes and saying less is more attitude. Anyway, take a look at this vid and I think you will get my point.... - Riffmaster
