The Magic on Della Mae’s latest is no Accident. 

For album No. 5, the bluegrass quartet – guitarist Celia Woodsmith, fiddling mandolinist Kimber Ludiker, bassist Vickie Vaughn and guitarist Avril Smith – recruited producer and Steve Martin collaborator Alison Brown, who also pitches in on banjo and guitar, to make an LP rooted in bluegrass but also flirting with pop on “Nothing at All” and country and western on “What You’re Looking For.”

Yet the group, with its sunshiny harmonies, never strays too far from its aural groundcover, bookending the 10-track offering with the wide-eyed wonder and lush instrumentation of the title track and the joyful acceptance of the a cappella closer that is “Takes all Kinds.”

“We all start with something/no one comes from nothing/it took a millennia to get you here/you’re a magic accident/the way that fate bent/with a little carbon and gravity,” the women of Della Mae declare on the former, which sets the tone for Magic Accident and its songs of existentialism (“My Own Highway”) and genetics (“Family Tree”) that follow.
