I went to the Hook and Ladder Theater & Lounge in Minneapolis to connect with this up-and-coming Minnesota duo about the origins of their act, their ties to the region's music community, and what they're looking forward to at the upcoming Amerigrass festival. You can hear Dellwood's intriguing modern indie take on old-time music on October 7: They're one of 7 acts performing at Amerigrass, a one-day festival taking place at the Hook.
