Out of Boston, Narrow Waves is a new indie-pop band whose alternating male/female vocals form a striking contrast. The two vocalists take turns singing about themes pertaining to love and relationships, while shimmering synth patterns and understated guitar riffs back them up to round out the band’s sound, which could be compared to R.E.M. from the ‘Out of Time’ period. The band played their second ever show on May 28 at Cantab Lounge. —Henry Solotaroff-Webber
