These Philly rockers conjure an ambling drone that conceals real pop hooks and allows classic-rock colours to seep through. Main man Adam Granduciel gets plenty of Dylan comparisons, but 'Slave Ambient' feels like a more back-alley Byrds filtered through a gauzier Spacemen 3 lens. The chugging 'your love is calling my name' drives that road for six blissful minutes, but their best song, 'baby missiles' - in a different version here than on 2010's 'Future Weather' EP - overlays a synth aura, like '80s-era Springsteen with a splash of Kurt Vile. it's vexing in exactly the right way.
