Treehouse formed in 2001 when leader Terry Tucker, keyboards, and co-founder Ardyth Gilbertson, percussion, began playing with conga drummer, Butch Sanders. Since then, they have added Matt Robinson, guitar and John Quintanilla, bass. Everyone sings. Though Terry writes the majority of the songs, the Treehouse repertoire includes original songs, instrumentals and arrangements from everyone in the group, along with covers of hit pop, rock, reggae, Latino and folk songs, done Treehouse-style.

Treehouse plays at festivals (Mountain Stage New Song Festival, Country Roads Folk Festival, West Virginia Wine & Arts Festival, Shepherdstown Street Fest, Peace & Unity Festival, Rolling Ridge Music Fest, Peace in the Valley Gathering), quiet listening venues (Opera Houses, Riverhouse Concert Series, Coffee Shops), and a variety of pubs, clubs and private parties. The band is down to earth and loves to perform and have fun with each other and their audience.
