Portland, Oregon-based pop folk outfit Blind Pilot have come a long way over the past decade. Originally conceived and nurtured as a duo by lead singer Israel Nebeker and drummer Ryan Dobrowski, the band has expanded to a six-piece and moved from playing hastily arranged, self-promoted gigs to headlining celebrated music halls like the Kessler. Much of this notoriety stems from the success garnered by 2011's We Are The Tide, an often rollicking, yet at times hushed affair that conjured the disparate elements of artists like Gillian Welch, the Avett Brothers and the Decemberists. The band's latest release, And Then Like Lions, is a lushly reflective meditation on the swift and uncompromising passage of time. With lyrics that are at times heady and ruminative, the contrasting musical arrangements flow along with ambling grace and charm. It's a formula that has garnered much industry praise and made believers out of many. As Friday's sold-out show indicates, Blind Pilot have fostered a sense of community among their fan base and created a near-perfect setting for singing along and swaying back and forth in time, a drink in one hand and the other intertwined with a loved one.
