One of the keys to the band's success, Quinn said, is that its members all like the same kind of music. One will suggest a song, and it's almost always met with approval from the others.
It also helps that the group has a "nice blend of harmonies," according to Wood, and that members have been in bands before.
In fact, that experience has helped land the band where it is today, which is largely playing at benefits and outdoor pavilions.
"We like the town park thing," Quinn said. "We all did that nightlife thing at one time or another."
"At a concert, people are coming to enjoy the music," Wood said. "It's so fun for us, and people will come up to us and say, 'We had a great time.'"
Washington County Line's performance at the Niskayuna Town Hall Gazebo is part of the town's summer free concert series.
The show starts at 7 p.m.
