Coyote Bones’ Gentleman on the Rocks: Since Bright Eyes enraptured the indie world, Omaha has become a musical mecca of sorts, and this project from Jet by Day’s David Matysiak is the latest team effort from Nebraska. With help from members of Neva Dinova, The Faint, Tilly and the Wall, and Flowers Forever, this debut is jangly, melancholy, and fun, and equal parts poppy, subdued, and synthesized.
