The songs of singer-guitarist M. Ward seem to drift in on the crackling radio waves of a distant time. Warm and intimate, his largely acoustic and usually spare arrangements are a tribute to what Ward sees as the greatest era for American music: the 1950s and early ’60s, when singers like Buddy Holly and Roy Orbison infused country-rooted pop with honesty and romance. Ward’s latest album, Hold Time, continues this tradition, with a gorgeously produced mix of finger-picked guitars, upright bass and shuffling rhythms, all tied together by his achy voice.
