Since The xx rose to new age, electronic fame all those years ago, mountains of boy/girl, low key electronic groups have been lining up and waiting for their big hit. One of those groups is softly-named I Will, I Swear from Belgium. Two tracks of theirs are currently being fished for by listeners throughout the blogging world — “Sleep” and “Long Days” both have slow, emotionally-stirring verses which eventually rise to a fulfilling intensity. Focusing on a simple, minor-drenched piano progression, quiet string section and wispy, delicate vocals, I Will, I Swear are touching hearts all over the globe.
