As more than 300 folks filled the Baltimore Museum of Industry to enjoy an evening of music and revelry, the atmosphere at Hoodstock XXI still harked back to its much smaller beginnings when decades ago, Russ Causey started the Woodstock-inspired party with his band, Roses n Rust, performing in his backyard.The party has continued to grow in the 21 years since, as a fundraiser for Unified Community Connections, a nonprofit that provides support to people with disabilities.

Every year, the crowd has grown along with the roster of local bands that perform, still headed by Roses n Rust.

Other than the excuse to wear tie-dye and love beads, UCC president and CEO Amy Kreitz said it’s the party’s original down-to-earth feeling that continues to appeal to folks.

“It’s the music. It’s the relationships. And it’s the jeans,” she noted, with a laugh.
