Speaking in a lightly sardonic manner, Hall was quick to point out that the group's name is not the Glen Hall Trio. It's Trio Muo. (Muo is from the Greeks. It means closed eyes and a closed mouth that speaks no words as a person goes on an inner journey.) So as these musicians go inside, then with each other, maybe they can connect with the audience, Hall said.

But since this is music, and not philosophy, let's note that these conceptually advanced gentlemen play with a very mellow sound. Drummer Joe Sorbara, an active presence in Toronto's free improvising community, drew sympathetic music from all parts of his drum kit as he supported and interacted with the group's flowing creativity. 'Clear and intelligently probing' describes Glen Hall's soprano sax, flute and tenor playing. And in the case of bassist Michael Morse, a sweet tone and attractive clarity of mind distinguished his playing throughout the concert.

The core influence of this music is, above all, Thelonious Monk, Hall stated, as well as players like the pioneer avant-garde trombonist Roswell Rudd and the composer/keyboard player Carla Bley.
