For a guy named Stelth, playing a surprise, unscheduled show at a place called The Hideout Brewing Co. sounds, well, perfect.

Singer and multi-instrumentalist Stelth Ulvang, a member of the platinum-selling Colorado folk-rock band The Lumineers, unfurled an impromptu performance early Monday night upstairs at the cozy Grand Rapids brewery and pub.

Not exactly hiding out, Ulvang was actually passing through Grand Rapids – and playing for tips – while on a September solo tour before The Lumineers kick off an overseas tour in November.
