Baltimore’s Future Islands reached peak exposure in 2014 with their excellent album Singles and a “Letterman” performance that showcased bandleader Samuel T. Herring’s captivatingly GIF-able dance moves. In their off-time, Herring, bassist William Cashion and a slew of other Charm City shakers write, record and perform as The Snails, a semi-serious project more indebted to the early days of trebly rock and roll than to the electronic stylings of Future Islands. Herring’s theatricality and Cashion’s intricate grooves are still very much present, but the use of horns lends itself to a different type of danceability. The group recently released their debut LP, and will play the Caledonia Lounge in support of it.
