In part to return Cliff Miller’s favor of hosting some meals for Castleton Festival participants at his Inn at Mount Vernon Farm in Sperryville, a contingent of singers and musicians – including on this most recent visit the festival’s world-famous founder, Maestro Lorin Maazel, and general manager Nancy Gustafson (shown with Miller, who is on the right, in the bottom left photo) – came to perform at Miller’s grass-fed livestock farm, including Castleton’s Emily Becker and Sarah Simmons (in top photo). But . . . perform for whom? The livestock – cows and pigs, mostly. Results were mixed, though the performers were undaunted. Miller also wondered how a capella voices would sound in the enormous 1917 former dairy barn he’s been renovating (and which has been the site of one wedding reception and more to come in the fall). There, even Maazel – who took a turn himself singing in one of Miller’s pastures – was impressed by the barn’s acoustics. Now all it needs is . . . some less-than-100-degree weather.
