Larkin Poe + Jack Harris

Sisters Rebecca and Megan Lovell turn out an Elvis Costello-approved blend of melodic Southern rootisiness of the sort that'll probably sit better with fans of Dixie Chicks than Devon Sproule, as they tout 'Fall' and 'Winter' (out April 18), two seasonally themed mini albums that follow 2010's 'Spring' and 'Summer'. Plus poetic young Welsh folk songwriter Harris.
