This is a golden age for fans of beardy guys who infuse their indie-rock sound with rich vocal harmonies that recall the heady days of Crosby, Stills & Nash. The L.A. band Dawes may be led by singer Taylor Goldsmith, but the group's layered backing vocals are just as much the star of its sweetly melancholy debut album, 'North Hills.' Here, Dawes performs live at the Newport Folk Festival in Newport, R.I.
