On “Lemonade,” the big gulp of bittersweet, noisy pop that is this EP’s finest track, singer Justin Giles is simultaneously psyched up and disoriented—just like the music that envelops him. “Where did you take me?” he asks. “These kids are drunk and they don’t like guitars.” If he’s at a party where the kids don’t dig six-strings, he’s definitely in the wrong place. On their first release since 2009, these Chattanooga rockers have a field day with guitar textures, moving from pretty and pulverizing to hauntingly sedate often in the span of a single track. As a vocalist Giles bides his time, singing towering choruses precisely when needed and then fading back into his beloved squall.
