It comes as no surprise while listening to Til I Prune that singer/guitarist Aaron Calvert and bassist/guitarist Mikel Garmendia have played together for a decade. Calvert recently released a solo album of children’s songs, but this mellow, well-worn collection skews more toward the shadowy side: think Sparklehorse, Red House Painters, and Tom Waits incubating over a lifetime.
