GLO-TREE is an improvised ambient duo featuring GNM (guitar) and Trē (flutes). Their sound is calm, unique, and elevates the mood of an event. They are performance staples in the Pittsburgh scene and frequent venues like The Space Upstairs, Bantha Tea Bar, and The Government Center.

They are currently working on their debut EP set to be released October 2024. It features expansive soundscapes, expertly crafted by Pittsburgh legend Herman Pearl, with melodic and exploratory playing from both Trē and Gloria.
