Dawes is one of those rare rock acts -- think Kings of Leon or Ray LaMontagne -- that glides effortlessly between popular music and a believably vintage-sounding aesthetic. Singer Taylor Goldsmith’s analog lead vocals may be unique for the ProTools-era listener, but his delivery is, unquestionably, a chip off of Jackson Browne’s old block. (Somewhat ironically, the band has backed Browne on tour). Which, in recent years, has left us scratching our heads. Does this band have an authenticity problem, or is this the sound of rock music’s Next Big Thing?
