Dave lives in Seattle now and has for a long time, so some people from the area are claiming DMB as a Seattle group, but IMO South Africa or South Carolina or South Dakota can have him (and bring Macklemore), DMB sucks!
We can claim Allen Stone, who is from Eastern WA, and Fleet Foxes, Band of Horses, Odesza, Presidents of the USA, Queensryche, and Sir Mix A Lot. I will definitely give it up for the Seattle music scene, we have it pretty good
