Detroit’s the Hard Lessons have proven skillful at both stompin’ garage rock and intensely catchy pop tuneage, and on this, their third full-length, core members (and newlyweds) Augie Visocchi (guitars/vox) and Korin Louise Visocchi (keys/vox) celebrate both styles with equal fervor. From the Hives school of rock, the swooping guitars and buzzing synths on “Sound the Silent Alarm” ride along on a thudding back beat, “Ko Ko” Visocchi’s backup vocals teasing the song into an uproar. The rousing title track starts with metallic guitar riffage (we get a whiff of Sabbath here) before the tambourines and vintage keyboards start chasing Augie’s voice through the ether; it’s a great bit of garage pychedelia. They playfully push the genre envelope on tracks like “Manoogian Zoo,” where a gauzy, 4AD-ish 90 seconds of ethereal pop morphs into a slightly heftier — yet still delicate — bauble with a chugging, fuzzy bass line, and on “Roma Termini,” a giddy, disco-powered number. Their most cohesive outing yet, Arms Forest is one of the strongest, multi-colored offerings this year from the indie rock realm.
