Presenting bluegrass and Celtic influences suffused with pop sensibilities, Montréal’s the Bombadils are typically categorized as chamber folk. But the quartet brings an elite musicality in the form of classical and jazz chops honed at McGill University, where they met six years ago. The culmination of those influences and abilities manifests in the band’s 2015 sophomore record, Grassy Roads, Wandering Feet. The album is drawing raves in Canadian and American folk circles for its evocative songwriting and exceptional performances. The Bombadils play a string of Vermont shows this week: Thursday, September 24, at the Skinny Pancake in Burlington; Saturday, September 26, at Phantom in Waitsfield; and Sunday, September 27, at the Skinny Pancake in Montpelier.
