At times, San Fermin’s sophomore effort, Jackrabbit, doesn’t feel like the work of eight musicians. The album, following the Brooklyn, N.Y., band’s 2013 debut, has moments of quiet singularity. Singer Allen Tate, whose voice recalls the gravely croon of The National’s Matt Berninger, drives the emotional gravity of tracks like “Emily” and “Astronaut.” The lush orchestral buoyancy of the rest of the musicians and the vocals of new addition Charlene Kaye bolster bandleader Ellis Ludwig-Leone’s overall vision, particularly on boisterous number “Ecstatic Thoughts.” San Fermin are perhaps most powerful during the spaces between their grandiose surges, and Ludwig-Leone and his band know how to balance those highs and lows within the songs: “Woman In Red” shifts between sparse, hypnotic verses and layered, cinematic choruses, resulting in a more effective expression of aching emotion. The album almost feels like Sufjan Stevens is composing music for The National, although there’s still something inexpressibly and evocatively original about San Fermin’s songs.
