Anyone with a Mumford fetish and access to a mandolin can start an indie-folk band, but not all modern-day pluckers and strummers are created equal. That was apparent earlier this year when Swear and Shake stopped by HQ for an in-studio performance. What makes these Brooklynites great: They can flat out sing, and as Adam McHeffey, Kari Spieler and Shaun Savage harmonized on 'Daggers,' all the worker bees in the office slipped off their Bluetooths and headphones and let the sweet sounds flow into their noggins.

Sure, productivity fell 25 percent that afternoon, but everyone left happy and relaxed, and we made it up the next day. Such is the power of Swear and Shake, who've shared stages with the likes of the Lumineers and G. Love & Special Sauce and played such major festivals as Mountain Jam and Governors Ball. The foursome released their debut LP, 'Maple Ridge,' in 2012, and in May, they returned with 'Brother,' the debut single from their eagerly anticipated sophomore set.

Check out 'Daggers' below, and if you're in NYC this evening (Oct. 10), catch 'em in action at Drom.
