If early-'90s alt-country bled into postmillennial adult alternative music, it might sound like Green River Ordinance’s 2012 studio album, Under Fire. The instantly catchy “Dark Night” opens with triumphant, fist-pumping drive and vacuum-tight three-part vocal harmonies, sounding like a pumped-up Crosby, Stills & Nash. With “New Day” the band reveals a more original sound, with stuttered rhythms and guitars that balance rootsy tones and more innovative sounds (akin to those of U2’s The Edge). With the slower “Resting Hour,” it’s evident that Josh Jenkins’ slightly textured vocals were meant to sing ballads. Here he has room to stretch his range and exercise restraint, letting listeners home in on the subtle nuances of his rich timbre. The band braids post-grunge grit with barbed power pop in the soaring “Heart of the Young,” a standout stadium-rock arena anthem. The bonus track “Dancing Shoes” returns the band to the sound of its acoustic EP The Morning Passengers.
