I've recently fell in love with this tuning but outside of John Fahey, I can't think of any DADGAD songs. Lil' help?
white summer black mountain side
Attitude- John Butler Trio
Treetop Flyer - Stephen Stills
the intro to Remorse Is For The Dead - Lamb Of God
isn't kashmir in dadgad?
many of john butler trio and bert jansch songs are in that tuning
Stan Rogers does a lot in that tuning!
Some of Led Zeppelins acoustic songs are in that, as well as kashmir
Most of Justin King's stuff is in DADGAD
The master, the king of DADGAD is Pierre Bensusan! UNREAL! 'En Route To Scarbrough' Is amazing, the only problem is you won't find any of his good songs on this site, he's not very well know. But everything he does is in DADGAD. You should pick up one of his albums. 'Intuite' (think that's how you spell it) is the one I have.
