Milwaukee quartet Longacre makes adult Americana that is perfect for coffee bars. Acoustic guitar, lap steel and keyboards maintain a balance between roiling and restraint. Singer Claire Chin’s sometimes-enigmatic, philosophical lyrics fit with a meticulous tautness over aural lulls and eruptions, like Sarah McLachlan or Natalie Merchant with a warmly approachable archness. With a dash of reggae here and a pinch of psychedelia there, Longacre has crafted a latte soundtrack that also appeals to those who listen with more focus. Either way, it’s professional and alluring.
