It's been 10 years since the band Future Islands performed its first Tiny Desk concert. Now its four members are gathered not too far from their Baltimore base in Carroll Baldwin Memorial Hall, sans desk. "We lost the desk," singer Sam Herring tells us with a smile. With drummer Michael Lowry on the tiny stage, the rest of the band — including bassist William Cashion and Gerrit Welmers on electronics — took to the floor, allowing Sam Herring to make his moves and sing his heart out. This music is clearly for the head and the feet.
