With it’s euphoric energy and sing-along chorus, “We Come Running” introduced Youngblood Hawke with a breakthrough single that brimmed with youthful optimism and borrowed the bright sonic palate of ’80s synth-rock. The self-titled debut album from the L.A. quintet possesses similarly unhinged creative oomph, using wailing tom-toms, group-sung countermelodies, and blasting synthesizers to fuel every catchy hook. “Say Say,” “Stars (Hold On),” and “Rootless” are some of the triumphant standouts that would play well alongside convincing indie rock optimists like Phoenix and Edward Sharpe & The Magnetic Zeros.
