D Dorian in DADDAD open tuning

Played on a beautiful red Gibson acoustic, Jimbo Kennedy demonstrates the use of his open tuning guitar scales book with an improvisation in D Dorian. This tuning, DADDAD, is sometimes called 4&20 after the CSNY song that popularized it. Judy Blue Eyes Suite is another great example from the same band.
