Last year, after posting some fingerstyle acoustic guitar clips on Instagram, Luke Brindley was startled by the response. “They sort of went viral,” he says, on the phone from his home in Northern Virginia. Several hundred followers swiftly multiplied, and their ranks approached 20,000. That’s when Brindley found himself thinking, “I might be onto something here.”

The upshot? “Invitation To Joy,” Brindley’s first collection of instrumental pieces. It’s not a solo recording: Renowned fiddler and mandolinist David Mansfield contributes to a strong lineup. Nor is it a dramatic departure for Brindley, a veteran singer-songwriter known for his exceptional guitar work. Yet “Invitation to Joy” quickly stands apart, brimming with self-penned, richly textured pieces that make imaginative use of alternate acoustic tunings, electric guitar and Dobro. Elements of Celtic, country, blues, jazz and world music play a role, creating shifting moods and appealing contrasts.

Along with his brothers Daniel and Jonathan, Brindley owns and operates Jammin Java in Vienna. He’ll perform selections from his new album this weekend during the club’s multifaceted 15th anniversary celebration, in addition to collaborating with several notable artists and toasting the club’s loyal supporters. The venue’s success is more easily understood than attained, Brindley says: “ I think we’ve really created a community of music lovers and both local and touring performers.”
