The Wood Brothers ’ sixth outing, ‘One Drop of Truth,’ dives headfirst into a deep wellspring of sounds, styles and influences. Whereas their previous outings have often followed a conceptual and sonic through-line, here the long-standing trio featuring brothers Oliver and Chris Wood along with Jano Rix treat each song as if it were its own short film. The end result is undeniably The Wood Brothers’ most dynamic recording to date.
