On Reagan Boggs’ new album, Quicksand, the country singer-songwriter examines “those mired living a routine existence, only to wake up one day wondering whatever happened to their dreams.” It’s a road she has walked herself, having left the music business behind in 2009 to care for her newborn son. “You kind of go through a period where you learn about who you are outside of music,” Boggs says. “You find interests that you didn’t even know you had. But it left a really big hole there.” The quicksand theme runs throughout her new work, revealing everything from insecurity to revelation — all in that rich, country twang. Boggs performs at the Lexington Avenue Brewery on Friday, April 4, at 8:30 p.m. The Coalmen also perform. $8. lexavebrew.com. Photo courtesy of the artist.
