Within the past year, Brooklyn-based Spires grew from 22-year-old Matt Stevenson’s bedroom project into an expansive four-piece. With the increase in members came an enhancement to Spires’ sound, lifting Stevenson’s spectral bedroom pop to soaring psych-pop heights. For its first two minutes, their new track “Sterling” is a bouncily accessible effort with an urgent guitar lead reflecting Stevenson’s tripped-out vocal melody. As “Sterling” progresses, Spires’ adventurous tendencies become heavily prevalent. The final minute sees several bursts of innovation as new arrangements serve as cohesive continuations of the initial verses; whirring organs and lavishly constructed guitar interplay remind of Tame Impala, a comparison any aspiring psych-rocker should be proud of. We look forward to hearing the follow-up to “Sterling” next month.
