Watter keyboardist Tyler Trotter is also the owner of three craft beer establishments in Louisville: Holy Grale, Gralehaus, and Beer Store. He and Zak Riles, also of Watter, met Stillwater brewer Brian Strumke at a brunch at Holy Grale about a year ago, and the rest was history. “From that point on it was really just a matter of managing to find some time within everyone’s busy schedules to make it happen,” Trotter said. “We wrote and recorded the song over a couple days in late September and everything else just sort of fell into place.” In this case, “everything else” also meant getting Will Oldham onboard, and the resulting track is like the most spaced out Bonnie “Prince” Billy song ever. The sour smoked wheat ale associated with the project will launch on April 25, and given Stillwater’s track record as an artist collaborator, it feels safe to assume it will be great.
