Well, what I would really love to hear is a Mark Knopfler album that is kinda mix of the music from the Delta, the Swamps, Bluegrass with a little punch of Southern Rock.
With guest peformances of Jerry Douglas on his weissenborn, Bela Fleck on his deering crossfire electric banjo, Derek Trucks sliding around on his Gibson SG, Paul Franklin on his "box" (You and Your Friend) and Sonny Landreth. Plus a vocal duet with Chris Rea.
Anyway, i think it will be the same band so I am quite sure it will be celtic.
