The two members of Hexes and Ohs consist of Edmund Lam and Heidi Donnelly, who were high-school sweethearts who experimented and created their own musical sound.
While with this band they recorded two albums and through the 90’s transformed from an East Coast pop style to a more electric sound.
Donnelly and Lam then created the duo Hexes & Ohs shortly after A Vertical Mosaic was disbanded.
The album contained a combination of vocals, guitars, and synthesizer; it placed in the top ten on the Canadian campus and community radio charts in June that year.
Donnelly and Lam have opened for Mates of State, Sloan, Aurevoir Simone, Tokyo Police Club, and Pony up!
