As a trio, The Lumineers began playing at a gritty basement club where Denver’s most talented songwriters gathered every Tuesday for an open mic. The Lumineers' sound took shape - an amalgam of heart-swelling stomp-and-clap acoustic rock, classic pop, and front-porch folk. In 2011, an eponymous self-recorded EP led to a self-booked tour, and before long The Lumineers started attracting devout fans, first across the Western U.S., then back in their old East Coast stomping grounds. Young, old and in-between, they’re drawn by songs like “Ho Hey” and “Stubborn Love,” Americana-inflected barnburners in the vein of the Avett Brothers and Mumford & Sons. They’re drawn by songs like “Slow it Down” and “Dead Sea,” slow, sultry ballads that suggest the raw revelations of Jeff Buckley and Ryan Adams. They’re drawn by the live Lumineers experience—a coming-together in musical solidarity against isolation, adversity and despair. The roots revival of the last few years has primed listeners for a new generation of rustic, heart-on-the-sleeve music—the kind that nods to tradition while setting off into uncharted territory. The Lumineers walk that line with an unerring gift for timeless melodies and soul-stirring lyrics. It will all be on display soon, on the band’s first full-length album, due in March.
