If we have to do a reprise of the late 60s and early 70s — complete with presidential impeachments, we might as well get the soundtrack, too. Caitlin Anne Webster’s got the kind of rich, clear singing voice that would have made every beatnik drop their espresso and every hippie drop their doobie — and make you drop your vape pen. “Powhatan River Blues” luxuriates in time, space, and musicality. It’s a simple finger-picking pattern that showcases Webster’s poise and insightful lyrics. Clocking in at five minutes, it’s a reminder that we deserve to spread out and take things slow as much as possible.
